Annotation
When observations are made to estimate properties of a geospatial feature, in particular where the value of a property varies within the scope of the feature, a spatial sampling feature is used. Depending on accessibility and on the nature of the expected property variation, the sampling feature may be extensive in one, two or three spatial dimensions. Processing and visualization methods are often dependent on the topological dimension of the sampling manifold, so this provides a natural classification system for sampling features. This classification follows common practice in focussing on conventional spatial dimensions. Properties observed on sampling features may be time-dependent, but the temporal axis does not generally contribute to the classification of sampling feature classes. Sampling feature identity is usually less time-dependent than is the property value.

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!
