Chris, I assume you mean XML Schema. There is no official effort underway to express the EAD DTD in XML Schema. Rationale: XML Schema has only recently been elevated to "recommendation" status by the W3C, 2 May 2001. Robust software support for it is not yet available. EAD and other complex DTDs (such as DocBook and TEI) make extensive use of parameter entities in their designs. Parameter entities do not map directly into Schema structures, and thus to accomplish the same or similar semantic and structural objectives in Schema requires rethinking and "re-engineering." Since the re-expression of EAD into Schema will require a major effort, the EADWG has deferred making a decision concerning Schema until there is major support for it as demonstrated by significant software developments and implementations, and there are clear benefits to having an EAD Schema. Speaking for myself, I suspect EAD will be expressed in Schema at some point, but not yet. The data typing and other constraints enabled by Schema are potentially quite useful, especially as the archival community begins to extend consensus on what constitutes good archival description.
