All nillable elements are now not abstract and have the STCReference attribute group. Where referencing of whole substitution groups (through their head elements) makes sense, this has been extended to those head elements. This means that those head elements are not abstract anymore and some types had to have their abstract attribute revoled as well. That is regrettable, but I think we ended up with a more consistent system where the referencing is more functional, too. Revision 2.20 2007/11/13 20:52:59 arots Made position angle elements in size2Type and size3Type nillable. Revision 2.19 2007/10/11 18:29:41 arots Added Handedness attribute to a Frame's Flavor. Added support for identifying ID and IDREF attributes through ID_type and IDREF_type attributes; this helps applications like registry to identify those kinds of attributes without having to refer to the schema. Added GPS time scale. Revision 2.18 2007/06/15 14:03:43 arots Added Resolution, etc. substitution groups to support Characterisation. Completed orbital elements specification. Revision 2.17 2006/11/16 22:12:43 arots Added some missing frame_ids, e.g., in the Areas. Revision 2.16 2006/08/01 21:20:59 arots Made coordFrameType derive from stcBaseType. Revision 2.15 2006/07/28 14:02:27 arots Reworked the inheritance schemes for CoordSys, Coords, and CoordArea: mainly though extension. In general there is a generic type (for non-STC coordinates), a Pixel type that adds pisel coordinates to generic, and an Astro type that adds time, space, spectral, and redshift to generic. In addition, coordinate transformation specification is now fully integrated in the schema. Revision 2.14 2006/05/09 20:50:50 arots Added support for generic frames (frame_id, etc.) Added ucd attribute to the baseSTC attribute group. Revision 2.13 2006/04/28 20:57:30 arots Made elements nillable where necessary. Revision 2.11 2006/03/30 23:33:14 arots Fixed reference to Region in region operation types. Revision 2.10 2006/03/23 21:59:15 arots Removed STCCoordinate[List] and STCRegion[List] elements. Renamed the stc[Coordinate|Region][List]Type to STC[Coordinate|Region][List]. Modeled STCCoordinate[List] type after STCRegion[List]. All of this should make life easier for Tamas. Revision 2.8 2006/03/03 14:44:09 arots Repaired dropped parts of stcRegionType and stcRegionListType. Revision 2.7 2006/03/01 20:58:22 arots STC Version 1.30: Removed anonymous types, added application public types for regions, introduced universal referencing model using Xlink. Revision 2.6 2005/02/25 19:30:24 arots IVOA version 1.20: Distinguished LSRK and LSRD, LOCAL_GROUP_CENTER replaces SUPER_GALACTIC_CENTER Subtle changes to force validation by Xerces-J2: slight obfuscation Added TEB time scale, warning on use of ISOTime (> 0001-01-01 !) Added reference spheroid to GEO_D, changed GEO to GEO_C Added discussion of planetographic vs planetocentric systems, right- and left-handed systems Removed GEOGRAPHIC CoordFlavor (is really 3-D spherical); added POLAR Revision 2.5 2005/01/05 14:22:11 arots Release Verion 1.10 Added Pixel Space; overhaul of inheritance and polymorphism Revision 2.4 2004/07/23 21:17:50 arots Modified ivoa schema locations; changed URN from nvo- to vo- Revision 2.3 2004/07/16 22:37:53 arots Release version v1.0. Revision 2.2 2004/07/07 16:16:22 arots Completed conversion to substitution groups. This version is ready for review. revision 2.1 date: 2004/05/23 03:32:59; author: arots; state: Exp; lines: +798 -1 Fixed line breaks revision 2.0 date: 2004/05/21 21:09:17; author: arots; state: Exp; lines: +1 -679 Reworking with substitution groups and generalized CoordSys & Coords. revision 1.10 date: 2004/03/31 21:20:30; author: arots; state: Exp; lines: +362 -218 Proper units and improvements. Revision 1.9 2003/08/06 19:31:04 arots Added time reference direction to time frame. Revision 1.8 2003/05/15 10:04:23 arots Allow multiple intervals, add fill factor. Revision 1.7 2003/05/08 20:28:19 arots Added spectral coordinate. Fixed intervals. Rationalized coordinate frames. Revision 1.6 2003/05/02 18:46:43 arots Removed coord_sys_id attribute from time interval. Revision 1.5 2003/04/30 16:55:58 arots Added CoordSpec to Resource and Search - was needed. Revision 1.4 2003/04/30 13:27:12 arots Fixed up change log, changed schema locations. Revision 1.3 2003/04/29 21:04:37 arots Trivial. Revision 1.2 2003/04/29 20:56:40 arots Completed new astronTimeType and proper handling of units.

| 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:
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! To buy a license, please follow this link: http://www.filigris.com/shop/ |
