Let's say I have a string of the form "a:b;c:d;" where there
can be any number of sub-parts of the form "x:y;", that I'd like
to parse using xsl:analyze-string.  With the following regex:

^(([a-z]):([a-z]);)+$

which matches indeed, I cannot use the regex-groups to retrieve
all values.  For instance the following:

     <xsl:analyze-string select="'a:b;c:d;'"
                         regex="^(([a-z]):([a-z]);)+$">
        <xsl:matching-substring>
           <group num="0" value="{ regex-group(0) }"/>
           <group num="1" value="{ regex-group(1) }"/>
           <group num="2" value="{ regex-group(2) }"/>

   Are my expectations wrong?  If yes why?  And if yes, is there
any general solution to this problem? (by "general", I mean not
recursing on the string and using substring on ';' because here
this is a simple delimiter)

    <xsl:analyze-string select="'a:b;c:d;'"
                        regex="([a-z]):([a-z]);">
      <xsl:matching-substring>
        <!-- now access groups here -->
      </xsl:matching-substring>
    </xsl:analyze-string>
