Yes, its the only way.

You might want to define a global variable for the uppercase and one for
the lowercase letters:

<xsl:variable name="uppercase">ABCDEFGHIJ...</xsl:variable>
<xsl:variable name="lowercase">abcdefghij...</xsl:variable>

than you can use

<xsl:value-of select="translsate($string, $lowercase, $uppercase)" />

when you maintain a one-to-one mapping between upper and lowercase you
can add as much additional characters as you like (e.g. &auml; and
&Auml;)

It depends, you should minimise the list of characters in the
upper/lowercase variable as good as you can. The runtime should be
O(length($string)*length($uppercase))

and I don't know how to make it any faster

Ask someone who knows the language, e.g. there is no uppercase version
of &szlig; in German.

BTW: my keyboard does not support the funky german characters, and I've
     therefor used html entites I hope you can read them ;-)
