That's the normal behavior: your xml boils down to
'<d><para>p 1</para> <para>p 2</para></d>', which as the same structure
as, for example, '<p><b>Hello</b> <i>World!</i></p>', where obviously
you would not want to discard the space between b and i.
The space would be discarded if it included a \n, try with
<d><para>p 1</para>\n <para>p 2</para></d>
The documentation is unclear about this, so I have updated it in the
development version of the module.
i have also added a 'discard_all_spaces' option, that discards spaces
more aggressively, namely it will discard all-space strings before a tag
(opening or closing), whether they include a \n or not. This would allow
indenting of your document.
The development version is in the usual places,
http://xmltwig.org/xmltwig/ and
http://github.com/mirod/xmltwig
