http://www.w3.org/Bugs/Public/show_bug.cgi?id=11179 --- Comment #6 from Michael Kay <mike@saxonica.com> 2011-02-08 15:31:20 UTC --- >Is there any property of XSD schemas that makes it difficult or impossible to solve the problem of working with documents conforming to multiple overlapping schemas? Or is the difficulty Michael Kay alludes to just a consequence of the rules imposed (or assumptions made) by XSLT 2.0? It's more the absence of a property than its presence. The XSD spec provides a simplistic view of a world in which there is only one schema. Within that schema, names are global and unique, redefines has ubiquitous effect, the meaning of ##notDefined is well-defined, nothing ever changes - it's a toy world. There's nothing to stop people developing a richer world view on top of this, one in which there are multiple schemas (identified by another level of indirection in naming), versions and variants and what-have-you. But developing a model for this, given how complex the XSD model already is, is a pretty daunting prospect, and I can't imagine anyone having the stomach for it. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
