Dear James: This note is in response to your mail to the XML Query WG on June 13 asking about DTD support in XML Schema. This is an official response, and has been reviewed and approved by the Working Group. Some of the WG members read your note as asking whether type information in the DTD could be used in creating the data model and for static typing. They asked that we remind you that XQuery issue 54 addresses this: " Issue 54 : Defining Behavior for Well Formed, DTD, and Schema Documents xquery-define-schema-variants) Description: We should specify the behavior of XQuery for well formed XML, XML validated by a schema, and XML validated by a DTD" Others, however, read your mail as asking whether a DTD can be used to define a collection of types whose names could be used in treat and cast operations and do specify function arguments. That is, we need to be able to refer to a DTD in the context similar to the production below for a schema. ContextDecl ::= ("namespace" NCNAME "=" StringLiteral) | ("default" "namespace" "=" StringLiteral) | ("schema" StringLiteral StringLiteral) On this issue there has been insufficient discussion and currently there is no firm position.
