I'd appreciate some examples showing burned fingers if anyone
has time.

beware though that that will get you burned again when you
start using
XSLT2 scented water.
xsl:value-of returns a text node with string value the
string value of the expression. This is subtly or not so
subtly different from a string.
It doesn't make so much difference in XSLT1 as the only way
to carry strings around is to put them in text nodes, but
in xpath2 you can have sequences of strings and sequences
of text nodes (and sequences that contain both strings and
text nodes) the rules for the two cases (and in particular
whether spaces are automatically inserted between adjacent
items) are different on the two cases.
