If by "nicer" you'll accept "more compact", this is what I direct my 
students to include at the top of their stylesheets:

<!DOCTYPE xsl:stylesheet [
  <!ENTITY lower 'abcdefghijklmnopqrstuvwxyz'>
  <!ENTITY upper 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'>
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="1.0">


Then, in your stylesheet you would have:

<xsl:variable name="pClubCaps"
              select="translate($pClub,'&lower;','&upper;')"/>

But as for functionality, translate() is all we have to work with in XSLT 1.0.

I hope this helps.
