I would recommend that you evaluate
normalize-space(saxon:evaluate($val)) once and put it in a variable.
Saxon doesn't eliminate common sub-expressions, and the saxon:evaluate
call is quite expensive; so is the "//xxx" expression that it's
evaluating.

Why don't you use xsl:choose/xsl:when instead of xsl:if, and put the
remaining code in xsl:otherwise?
