there was a time I'd have let that comment pass and assume the xsl-list
auto-documentation daemon would take over, but...

You want the first non-white space character of the first text
node that has a non white space character.

So reading the english from the end, and writing the xpath from the
middle

> that has a non white space character
[normalize-space()]

(this works as normalize-space() is normalize-space(.) which is a non
empty string if there is a non white character, and when a string is
used as a predicate it counts as true if non empty.)

>  first text node that ...
text()[normalize-space()][1] <!-- we'll drop the one later -->

> non-white space character of ..
normalize-space(text()[normalize-space()]) <!-- drop the one here due to
                                                xpath 1's first node
                                                rule for string functions -->

> You want the first

substring(normalize-space(text()[normalize-space()]),1,1)
