Yes, this works in the matches function. I guess the final } was being
matched by my .+, not by the final \}...

But now I need to do this:
<xsl:analyze-string select="." regex="^\s*\{([^\}]+)\}\s*$">
because I need to capture the the string between the braces. In Saxon this
gives me:
 XPath syntax error at char 7 on line 43 in {^\s*\{([^}: Invalid character
'^' in expression.

What am I doing wrong this time?
