Your string-to-codepoints example only works for ASCII upper/lower case
letters. It fails to recognize composed and decomposed diacritical characters
such as a combined uppercase A with a grave U+00C1, with an accute U+00C1, with
a circumflex U+00C2, etc. Yes you could detect these too with additional logic,
but matches() with a character class of \p{Ll}, \p{Lu}, \p{Lt} handles all the
messy details of Unicode.

Subject: Re: [xsl] Testing for upper and lower case
Is it possible to determine if the first
letter of a word is upper or lower case?
string-to-codepoints($str)[1]
will give you the codepoint of the first letter, you can then if its:
65 to 90 its upper case
97 to 122 its lower case
is that what you meant?
