intltool weirdness with xml attributes

[Shaun McCance <shaunm gmail com>]

>From the l10n.xml.in file in gnome-doc-utils:

<!-- Used as a header before a list of authors. -->
<_msg>
  <msgstr form='0'>Author</msgstr>
  <msgstr form='1'>Authors</msgstr>
</_msg>

And from bg.po (or any PO file of your liking):

#. Used as a header before a list of authors.
#: ../xslt/gettext/l10n.xml.in.h:1315
msgid "<msgstr>Author</msgstr> <msgstr>Authors</msgstr>"

So what gives?  What happened to my attributes?  This is happening
all over my strings.  These attributes are really necessary for the
plural forms and for providing multiple roles.  Having them disappear
is going to screw up the translations really bad.
