inclusions/exclusions/named groups

[Andrea Anders]

I am a amateur in xml and hope anyone can help me.

I try to transform a SGML-DTD into XML (I use MSXML-parser).
My questions are:

1) Neither SGML-inclusions nor -exclusions are allowed in XML!? How can I
   express this in XML?
   
   my sgml-dtd:

   <!ELEMENT LE - - ((a , b , c+) , d , e) +(f , g , h) >
   <!ELEMENT m - - (o | (#PCDATA))+ >
   <!ELEMENT c - - (l , (m | n)+) >
   ...
   <!ELEMENT e - - (i , (j , k)+) -(h)>

2) I tried it to bypass with named groups, but it failed. Named groups are
   not allowed too.

There are any ideas?

Thanks.
