SchemaContentElement

Any '''taxonomy schema content element''' in the model. It is either standard schema content, which is a representation of an element in the XML Schema namespace, or it is appinfo content. The schema root element, and imports and linkbaseRefs are not represented in this model. Neither are the topmost annotation and their child appinfo or documentation elements.

This schema content model offers the yaidom SubtypeAwareElemApi API. Note, however, that most schema content elements have no child elements, but type definitions typically do have descendant elements.

Due to the fact that this schema model hardly contains any URI references, it plays no role in DTS discovery. Also note that this schema model has no knowledge about XLink.

Schema content in this model needs as little context as possible, although substitution group "knowledge" must be provided in order to determine in general whether a global element declaration is a concept (item or tuple) declaration.

Several kinds of schema content elements in this model are easy to refer to from relationships, as source or target. Note that these "links" are semantically meaningful, and need no URIs to point to them.

Schema content elements are relatively easy to create on the fly, and could be part of the basis for easy programmatic taxonomy creation. Note, however, that the taxonomy creation algorithm must at some point worry about closure with respect to DTS discovery, and about containing the needed substitution group ancestry.

When creating schema content elements on the fly, keep in mind that the element and its descendants should agree on the optional target namespace. This is not checked!

TODO Remove linkbaseRefs from model.
