I did that (also merged ITS branch).  The relevant commit is:
http://git.sv.gnu.org/cgit/gettext.git/commit/?id=898e184a

Let me know if this change causes any compatibility problems.

The main obstacle was format-kde-kuit.c, which is shared between
xgettext and libgettexpo; while we can assume that libxml2 is always
usable from xgettext (through libgettextlib), it may not be usable from
libgettexpo.  So, I ported GLib's gmarkup.c as a local Gnulib module:
markup.  Currently, the use of the module is limited for libgettexpo for
some reasons (copyright, etc).
