Sometimes I would use this feature in this way:
<xsl:for-each select="keys('myKey')">
<xsl:if test="matches(., 'someRegularExpression')">
do some stuff here with key('myKey', .)
wich raises the wish for a shortcut:
key('myKey', 'someRegularExpression') or, more generic,
key('myKey', anyTwoArgumentFunction(myValue) as xs:boolean)
Maybe in XSLT 3.0
