[Bug 11061] New: [XDM 3.0] Support for XSD 1.1 inherited attributes


           Summary: [XDM 3.0] Support for XSD 1.1 inherited attributes
           Product: XPath / XQuery / XSLT
           Version: Proposed Edited Recommendation
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Data Model 1.1
        AssignedTo: ndw@nwalsh.com
        ReportedBy: mike@saxonica.com

As part of its support for XSD 1.1, XDM rules for creating an instance from a
PSVI should recognize the new [inherited attributes] property of an element
information item. Attributes present in the property should be converted to XDM
attribute nodes in the same way as defaulted attributes, so they are accessible
to XPath expressions.

The property arises when an attribute is specified in the schema with
inherited="true", which causes it to be visible (rather in the same way as
defaulted attributes) on its descendant elements.

The design of XSD 1.1 has made the assumption that we will do this, so that
XPath expressions used in Conditional Type Assignment have access to attributes
inherited from ancestor elements.
