I suspect this is an FAQ, and if so, feel free to point me to existing
discussion, but I'm curious as to what the most efficient/elegant way to
process a sequence of string tokens is.

In my specific case, I need to init-cap all the words in a string (I
don't need any sophistication like special case for conjunctions or

Here's the XSLT 2 function I came up with:

    <!-- Normalizes the case of titles based on the FASB-defined rules
for title case -->
    <xsl:variable name="titleTokens"
select="tokenize(string($titleElem), ' ')"/>
    <xsl:variable name="resultString">
      <xsl:for-each select="$titleTokens">
        <xsl:sequence select="concat(upper-case(substring(., 1,1)),
substring(., 2))"/>
    <xsl:sequence select="$resultString"/>

Which seems reasonably compact and understandable but I suspect that I'm
not doing things as cleverly or as "correctly" as I could.

Is there a better way to have written this function?
