Ok the problem is the doctype declaration on top of the macro files that
force the tal interpretor to enter html mode and as far as I understand
you can't have mix moded macros.

If you change the doctype declaration with the xml header and add the
xmlns declaration for tal, metal and i18n then everything's fine after.

See for instance the navigation macros :

http://svn.zope.org/Zope3/trunk/src/zope/app/rotterdam/navigation_macros.pt?rev=28163&view=auto

If you change the header like this then it can be succesfully included :

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml";
      xmlns:tal="http://xml.zope.org/namespaces/tal";
      xmlns:metal="http://xml.zope.org/namespaces/metal";
      xmlns:i18n="http://xml.zope.org/namespaces/i18n";
      i18n:domain="zope">
<body>


What kind of issue could we have changing the headers like this on all
the standard macros since it's xhtml already ?
