The xsl:analyze-string instruction in XSLT 2.0 does not work this way: it reports an error if the input is an empty sequence. So, for example, if there is no address element then <xsl:analyze-string select="address"> will cause a type error, but if the address element is present and empty, it will produce empty output. I propose we change this (a) for usability, (b) for consistency, and (c) to make it a little bit easier for implementations to reuse code between xsl:analyze-string and fn:analyze-string. 36941 1 mike 2010-07-16 10:49:12 +0000 Proposal accepted at the F2F meeting in Oxford (change xsl:analyze-string to accept the empty sequence in the same way as fn:analyze-string does).
