[Bug 1308] New: proposal: merge xsl:perform-sort and xsl:sequence


           Summary: proposal: merge xsl:perform-sort and xsl:sequence
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 2.0

As far as I can tell, an xsl:perform-sort is identical in all respects to
xsl:sequence except that in perform-sort (at least one) xsl:sort is mandatory
and in xsl:sequence xsl:sort is not allowed.

I would propose to remove xsl:perform-sort from the specification and allow
xsl:sort as a child of xsl:sequence (so that the semantics of xsl:sequence
become those currently used for xsl:perform-sort if it has an xsl:sort child)

This simplifies the specification (one less element) and makes the use of
xsl:sort more consistent. In other cases xsl:sort is optionally allowed as a
child of the containing instruction (eg xsl:for-each) with sorting occurring if
it is present, it is only in this case that there are two separate instructions,
one requiring a sort specification and the other not allowing it.
