<xs:annotation>

accepted by the service without returning an error
condition. Not providing this element or
specifying a value of 180 indicates that there
is no restriction.
</xs:documentation>

Not providing a value is the prefered way to indicate

<xs:annotation>
<xs:documentation>
The hard limit on the largest number of records that
the query operation will return in a single response.
Not providing this value means that there is no
effective limit.
</xs:documentation>
<xs:documentation>
This does not refer to the total number of spectra in
the archive but rather maximum number of records the
service is capable of returning. A limit that is
greater than the number of spectra available in the
archive is equivalent to their being no effective
limit. (See RM, Hanisch 2007.)

<xs:annotation>

in the query input. Not providing a value means
that the hard limit implied by maxRecords will be
the default limit.
</xs:documentation>
</xs:annotation>

<xs:element maxOccurs="1" minOccurs="0" name="maxAperture" type="xs:double">
<xs:annotation>
<xs:documentation>
The largest aperture that can be supported upon
request via the APERTURE input parameter by a
service that supports the spectral extraction
creation method. A value of 180 or not providing
a value means there is no theoretical limit.
</xs:documentation>
<xs:documentation>
Not providing a value is the preferred way to
indicate that there is no limit.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element maxOccurs="1" minOccurs="0" name="maxFileSize" type="xs:positiveInteger">
<xs:annotation>
<xs:documentation>
The maximum spectrum file size in bytes that will
be returned. Not providing
a value indicates that there is no effective limit
the size of files that can be returned.
</xs:documentation>
<xs:documentation>
This is primarily relevant when spectra are created
on the fly (see creationType). If the service
provides access to static spectra, this should only
be specified if there are spectra in the archive that
can be searched for but not returned because they are
too big.

<xs:complexType name="ProtoSpectralAccess">
<xs:annotation>
<xs:documentation>
The capabilities of an proto-SSA service implementation.
Clients may assume a particular interface for this type of
service based on historical convention; however, no
guarantees are made that the service is compliant with any
IVOA standard.
</xs:documentation>
<xs:documentation>
This capability is for spectral access services developed
prior to the completion of the SSA standard and,
therefore, are not compliant with that standard.

The category that describes the process used to
produce the dataset.

<xs:documentation>
Typically this describes only the processing
performed by the data service, but it could
describe some additional earlier processing as
well, e.g., if data is partially precomputed.

<xs:annotation>
<xs:documentation>
The largest search radius, in degrees, that will be
accepted by the service without returning an error
condition. Not providing this element or
specifying a value of 180 indicates that there
is no restriction.
</xs:documentation>
<xs:documentation>
Not providing a value is the prefered way to
indicate that there is no restriction.

<xs:annotation>
<xs:documentation>
The largest aperture diameter that can be supported
upon request via the APERTURE input parameter by a
service that supports the spectral extraction
creation method. A value of 360 or not providing
a value means there is no theoretical limit.
</xs:documentation>
<xs:documentation>
Not providing a value is the preferred way to
indicate that there is no limit.

This XML schema documentation has been generated with DocFlex/XML RE 1.8.0 using DocFlex/XML XSDDoc 2.2.0 template set.
DocFlex/XML RE is a reduced edition of DocFlex/XML, which is a tool for programming and running highly sophisticated documentation and reports generators by the data obtained from any kind of XML files. The actual doc-generators are implemented in the form of special templates that are designed visually using a high quality Template Designer GUI basing on the XML schema (or DTD) files describing the data source XML.
DocFlex/XML XSDDoc is a commercial template application of DocFlex/XML that implements a high-end XML Schema documentation generator with simultaneous support of framed multi-file HTML, single-file HTML and RTF output formats. (More formats are planned in the future).
A commercial license for "DocFlex/XML XSDDoc" will allow you:
  • To configure the generated documentation so much as you want. Thanks to our template technology, it was possible to support more than 300 template parameters (working the same as "options" of an ordinary doc-gen), which will give you an unprecedented control over the generated content!
  • To use certain features disabled in the free mode (such as the full documenting of substitution groups).
  • To enable/disable documenting of the initial, imported, included and redefined XML schemas selectively.
  • To document local element components both globally and locally (similar to attributes).
  • To enable/disable reproducing of namespace prefixes.
  • To format your annotations with XHTML tags and reproduce that formatting both in HTML and RTF output.
  • To insert images in your annotations using XHTML <img> tags (supported both in HTML and RTF output).
  • To use PlainDoc.tpl main template to generate all the XML schema documentation in the form of a single HTML file.
  • To use the same template to generate the incredible quality RTF documentation.
  • To document only selected XML schema components specified by name.
  • To remove this very advertisement text
Once having only such a license, you will be able to run the fully-featured XML schema documentation generator both with DocFlex/XML SDK and with DocFlex/XML RE, which is a reduced free edition containing only the template interpretor / output generator. No other licenses will be required!
But this is not all. In addition to it, a commercial license for DocFlex/XML SDK will allow you to modify the XSDDoc templates themselves as much as you want. You will be able to achieve whatever was impossible to do with the template parameters only. And, of course, you could develop any template applications by your own!
Please note: By purchasing a license for this software, you not only acquire a useful tool, you will also make an important investment in its future development, the result of which you could enjoy later by yourself. Every single your purchase matters and makes a difference for us!
