Now I know I'm being a pain, but when I use that I get:

Ignoring the AVT rules, the regex syntax allows { to be used without
escaping inside [], but not outside: outside [] it is reserved for use in
regex quantifiers such as x{3}. So it must be escaped as \{. So the regular
expression you want is
(\w|\{[^{}]*\})+
which is written in the regex attribute as
regex="(\w|\{{[^{{}}]*\}})+"
It might be less painful to do:
<xsl:variable name="regex">(\w|\{[^{}]*\})+</xsl:variable>
<xsl:analyze-string regex="{$regex}">
though sadly, I suspect that will prevent Saxon precompiling the regular
expression :-(
Better idea: use chevrons instead of curlies.
