Hi,
I am trying to create XML schema of custom markup language, enriched
by XHTML. In simplified version, the XML documet could look like that:

<a:alarm-manual
xmlns:a="alarm-manual"
xmlns:h="http://www.w3.org/1999/xhtml"
xmlnssi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="alarm-manual alarm-manual.xsd"
>
<h>Text ... <aar-value name="myName"/> ... text </h>
</a:alarm-manual>

In full version, the root element and document structure elements are
from custom namespace, the "formating" elements are from xhtml
namespace, and there are also some inline elements from custom
namespace.

I've tried to create XML Schema based on http://www.w3.org/TR/xhtml-modularization
, however I do not know whether it is correctly done. I have created
two new xsd files:
XML Schema driver: amml.xsd
and custom module definition: amml-module.xsd
(both files see below, of course other XHTML schema files must be
added)

Can someone with better knowledge of XML Schema and/or XHTML
modularization comment it?
Thanks a lot, regards, Martin
