[xsl] analyze-string regex

I am trying to use xsl:analyze-string to process a json response, the model of
which is fixed.

The target environment is saxon-ce, but I am using oxygen to get things

I was under the impression that the regex would perform multiple matches,
allowing me to generate a sequence of elements from a string containing
multiple objects that I match.  If that is true (the spec says it should be, I
think), then my regex is faulty.  Could you offer any suggestions about the
following, please?

When I use dot-all mode (@flags="s"), I get a single <option> corresponding to
the last object in the array.  When no flags, an empty sequence.  Any
suggestions appreciated.

My objective is to generate a sequence of <option> elements matching the json
