In the absence of a data-type attribute <xsl:sort select="@a"/> <xsl:sort select="@b"/> will sort <x b="2"/> after <x a="" b="1"/> in XSLT 1.0, but before it in XSLT 2.0. Specifically, XSLT 1.0 considers an empty sequence to be equal to a zero-length string in this situation, while XSLT 2.0 considers an empty sequence to collate before a zero-length string. Michael Kay 4339 1 Norman.Walsh 2005-06-23 17:23:56 +0000 At the 23 June telcon, the XSL WG decided that it simply wanted to document this incompatibility rather than reopen the debate about where () should collate. 4654 2 mike 2005-07-14 18:48:20 +0000 This incompatibility is now documented in the spec.
