xqdm-classes
this started as a minimal xml document model. to wit, from the original description: this is an absolutely minimal and nonconforming xml processor. it reads the main document entity, skipping all processing instructions, declarations, and definitions. it returns only the single element in the document. it recognizes entities for <>& and translates them on input and output. no other entites are supported.

xqdm-qnames
while formulating the documentation, i experimented with examples of confliciting (homographic) qnames by asserting conflicting bindings and enabling/ disabling incremental propagation. the cases where conflicting bindings are detected are exactly those where qnames are indiscernably homographic. that is within a given declaration scope. which means that content-based propagation of namespace bindings is permitted to constrain the namespace of content elements, since a conflict implies indiscernable homography.

20010803
xqdm-classes

20010805
xqdm-parameters
*namespaces -> *namespace-bindings*

20010809
xsd-types
new type implementation for non-symbol type names: for both xml schema and the xml query algebra, element and attribute identifiers contribute to types. identifiers may be modelled either as symbols or as clos instances. (see xml:code;xquerydatamodel;xqdm-namespaces.) thus the type system must support both symbols and instance names. which means that the type system must be independent of the cl/clos type system, which stipulates symbols for type names. this type system for xml schema datatypes uses various specialized forms of type-definition to describe the declared type information (primitive type stipulations, content model structures, text patterns) and to drive the document decoding and interpretation process. these type definitions are more elaborate than those (def-elem-type, def-elem-property-type) which suffice for simple xml-1.0 declarations. it is envoked implicitly when the processor recognizes a reference to an xml schema according to the terms of the xml schema spec, in which case the schema declarations take precedence over any dtd declarations present.
