Title: RE: XSD Schema : Standard APIs ?
I personally do not see a compelling reason to provide a DOM-based API. We basically can use XQuery to query the type system since it is supposed to use XSD (and its formalization) as the type system itself...
 
Best regards

The W3C DOM Level 3's "Content Models and Validation" module will define a generic API for dealing with the content model that a "schema" (broadly speaking, including DTDs, XSD, and in principle RELAX, XDR, etc.) defines, the "PSV Infoset", and at least some datatype support.  See http://www.w3.org/TR/2001/WD-DOM-Level-3-CMLS-20010209/content-models.html for the initial draft of this effort, and please comment to www-dom@w... if the functionality described in this draft does not meet your needs. 

I believe, though I'm not sure, that the W3C Schemas working group is working on a set of XSD-specific extensions to DOM Level 3 that would more fully support its unique features.
