xml-dev - What is the error in this XML doc.

[Thillai <thillai@ix.netcom.com>]

I have a XML file called x.xml and the content is

<?xml version="1.0" standalone="no"?>
<!DOCTYPE A [
  <!ENTITY ref SYSTEM "y.xml">
]>
<A>
&ref;
</A>

and y.xml, the content is

<B>123</B>
<B>456</B>

I am able to parse the Document with root node as A and two children nodes B. No error.


If I change the XML file x.xml to

<?xml version="1.0" standalone="no"?>
<!DOCTYPE A [
  <!ENTITY ref SYSTEM "y.xml">
  <!ELEMENT B (#PCDATA)>
  <!ELEMENT A (B*)>
]>
<A>
&ref;
</A>


and when I read the x.xml using readStream(buf) I am getting the following error.

c:\proj\x.xml: 9, 5: Content mismatch in `<A>'.  Content model is ``(B)*'.

I am not sure whether it is a valid XML doc or not. I belive without those two lines in
the DTD it is a well formed document. But when add those two rules it becomes
an invalid document.  Basically what I am trying to do is x.xml will have root element 
and y.xml will have the contents of the root element A.  Please give me an
idea what I am doing wrong and how it should be.  (I am using IBM XML parser.)
