Sorry, it turns out it's implemented for matches(), tokenize(), and

This is a real shame. :-(  An emotional rollercoaster of finding out
that this magic flag exists, only to find out it doesn't exist in
xsl:analyze-string!  I guess I'll keep exploring other options.

you should be able to get access to the feature using replace() I think. use replace with the nonstandard lookahead flag and a replace string which re-inserts the entire matched string, but with some unique marker such as @start@$0@end, then you can apply analyze-string to the resulting string without needing any lookahead markers as you can instead match the explicit @start@ and @end@ boundaries added in the first pass.
