The basic feature model is given by the gml:AbstractFeatureType.
The content model for gml:AbstractFeatureType adds two specific properties suitable for geographic features to the content model defined in gml:AbstractGMLType.
The value of the gml:boundedBy property describes an envelope that encloses the entire feature instance, and is primarily useful for supporting rapid searching for features that occur in a particular location.
The value of the gml:location property describes the extent, position or relative location of the feature.

This abstract element serves as the head of a substitution group which may contain any elements whose content model is derived from gml:AbstractFeatureType. This may be used as a variable in the construction of content models.
gml:AbstractFeature may be thought of as "anything that is a GML feature" and may be used to define variables or templates in which the value of a GML property is "any feature". This occurs in particular in a GML feature collection where the feature member properties contain one or multiple copies of gml:AbstractFeature respectively.

gml:EnvelopeWithTimePeriod is provided for envelopes that include a temporal extent. It adds two time position properties, gml:beginPosition and gml:endPosition, which describe the extent of a time-envelope.
Since gml:EnvelopeWithTimePeriod is assigned to the substitution group headed by gml:Envelope, it may be used whenever gml:Envelope is valid.

This XML schema documentation has been generated with DocFlex/XML 1.11 using DocFlex/XML XSDDoc 2.8.3 template set.
DocFlex/XML 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-quality 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 > 400 template parameters, which work the same as "options" of ordinary doc-generators. The parameters are organized in nested groups, which form a parameter tree. Most of them have their default values calculated dynamically from a few primary parameters. So, you'll never need to specify all of them. That will give you swift and effective control over the generated content!
  • To use certain features disabled in the free mode (such as the full documenting of substitution groups).
  • To select only the initial, imported, included, redefined XML schemas to be documented or only those directly specified by name.
  • To include only XML schema components specified by name.
  • To document local element components both globally and locally (similar to attributes).
  • To allow/suppress unification of local elements by type.
  • To enable/disable reproducing of namespace prefixes.
  • To use PlainDoc.tpl main template to generate all the XML schema documentation in a signle-file form as both HTML and incredible quality RTF output.
  • 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 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 (Full Edition) 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 that 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 results of which you could enjoy later by yourself. Every single your purchase matters and makes a difference for us!
