newer Enhydra 5.1 beta based on XMLC 2.2 final?

Alfred,

are you going to release another beta or rc (release candidate) of
Enhydra 5.1 that would be based on XMLC 2.2 final?

I'd like to try it out before you release final 5.1 (when it's going to
happen, by the way?) since currently I am stuck with heavily patched
Enhydra 5.0 (due to XHTML problems in stock Enhydra/older XMLC). I'd
like to upgrade to 5.1 (once it's released) but only if there is no
problem with XHTML and the other things I had to patch (I sent all my
patches to you and later also to XMLC guys so hopefully it will be OK
but I'd like to make sure and possibly submit a patch for the 5.1 before
its release).

Thanks.

Petr
