The xml regex seems ok for this. The docbook output is as follows:

(...)
pairs in this list are in the <literal>bundle.*</literal> namespace (see
(...)

The manpage output seems also correct:

(...)
would accept (with the
\fB\-\-file\fR
option)\&. The key\-value pairs in this list are in the
\fBbundle\&.*\fR
namespace (see
(...)

Strangely, the --file above is rendered correctly, but the bundle.*
below not. I do not know TROFF to assess what is going on. Has '*' a
special behavior in a bold span?
