[Bug 14734] New: [XSLT 2.0] Literal result elements should not be laxly validated

http://www.w3.org/Bugs/Public/show_bug.cgi?id=14734

           Summary: [XSLT 2.0] Literal result elements should not be laxly
                    validated
           Product: XPath / XQuery / XSLT
           Version: Recommendation
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 2.0
        AssignedTo: mike@saxonica.com
        ReportedBy: mike@saxonica.com

In the XSLT 2.0 schema for stylesheets, literal result elements are validated
against a wildcard with processContents="lax". Consider this scenario:

<xsl:template match="/*">
  <book>
    <xsl:if test="@isbn">
      <xsl:attribute name="color" select="'green'"/>
    </xsl:if>
  </book>
</xsl:template>

If there is a global element declaration for 'book', it is very likely that it
will not permit an xsl:if element as a child. Performing lax validation of the
book element would therefore report a validity error. I believe therefore that
literal result elements should be processed using a processContents="skip"
wildcard.

off-list by Norm Walsh)
