            Bug ID: 23544
           Summary: [XSLT 3.0] Component binding and xsl:original
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 3.0
          Assignee: mike@saxonica.com

Suppose that package W uses package V, and a component P' in W overrides a
component P in V. Now suppose that P' invokes P by use of the xsl:original
mechanism. Suppose also that P contains a reference to component A. How is the
reference to A bound?

In particular, suppose that A is public or abstract in V, and is overridden by
a component A' in W. Do we call A, or A'? (Either would be possible if A is
public; only the latter is possible if A is abstract.)

I think there will probably be fewer surprises if we treat xsl:original as
invoking "the component you would have invoked in the absence of the override".
This means that xsl:original invokes a component P" in which the reference to A
is (re-)bound to A'.
