           Summary: [XSLT 2++] Enhancement: apply-templates to atomic values
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 2.1
        AssignedTo: mike@saxonica.com

This is motivated by a suggestion from Andre Cusson on xsl-list, 2008-02-03.

It would be a useful generalization of the XSLT processing model to allow
apply-templates on atomic values. It is currently restricted to nodes. This
would allow a capability similar to typeswitch in XQuery, but with the
advantages of dynamic despatch (including the ability to override rules in a
customization layer, for example). It would effectively give XSLT polymorphism
over atomic types as well as over node types. 

This would require extension of XSLT patterns to be able to match atomic values
by type. A possible syntax might be match="type(AtomicType)".

The existence of such patterns would also be useful in the group-starting-with
and group-ending-with attributes of xsl:for-each-group, which are currently
restricted to use when grouping sequences of nodes.
