<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>
<xs:documentation>
A set of queryData parameters that is expected to
produce at least one matched record which can be
used to test the service.
</xs:documentation>
<xs:documentation>
The value should include all parameters required
for the test query but should exclude the baseURL
and the REQUEST parameter.

In brief, this includes:

fields

<xs:annotation>
<xs:documentation>
Fully specified queryData test query formatted as an URL
argument list in the syntax specified by the SLAP standard.
The list must exclude the REQUEST argument which is
assumed to be set to "queryData". VERSION may be
included if the test query applies to a specific version
of the service protocol.
</xs:documentation>
<xs:documentation>
If queryDataCmd is used to form a query, the default
value of WAVELENGTH specified above is not
used; if the test query requires WAVELENGTH it
should be included directly in queryDataCmd.
</xs:documentation>
<xs:documentation>
This value must be a string in the form of name=value
pairs delimited with ampersands (&amp;). A query may
then be formed by appending to the baseURL the request
argument, "REQUEST=queryData&amp;", followed by the
contents of this element.

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!
