RE: [xsl] Is normalization is optional?

["Michael Kay" <mike@xxxxxxxxxxxx>]

The default collation used for the eq operator is implementation-defined in
XQuery, but in XSLT it is prescribed to be Unicode codepoint collation. At
any rate, I thought it was - rereading, I'm not sure I can find that
explicitly stated. But if I'm right, then an XSLT processor is not licensed
to perform Unicode normalization before comparing two strings unless a
different default collation has been chosen. In Saxon you can select a
normalizing collation using

<xsl:stylesheet ...
  default-collation="http://saxon.sf.net/collation?decomposition=standard";

If you do this, the comparison you cite returns true.
