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
