In the beta the patch is:

in xtag-ini: grab #1 from ]...]

\long\def\xparseXMLescape !#1#2%
   {\if#1-%
      \if#2-%
        \expandafter\expandafter\expandafter\xxparseXMLescape
      \else
        \expandafter\expandafter\expandafter\xyparseXMLescape
      \fi
    \else
      \if#1[%
        \expandafter\expandafter\expandafter\xzparseXMLescape
      \else
        \expandafter\expandafter\expandafter\xyparseXMLescape
      \fi
    \fi#1#2}

\long\def\xzparseXMLescape[#1[{\parseXMLescape{#1}}

in xtag-pre: {CDATA]} => CDATA

\defineXMLescape [CDATA]
   {\skipfirstverbatimlinefalse
    \processtaggeddisplayverbatim{]]>}}

So, this way we keep the installable parser in place
