Additional declarations included directly in xml document

[Carlos Ramirez Palacin]

Hello,

I have a problem with the additional declarations in a xml document.
If I include the element pp declaration in my xml document

<?xml version="1.0" ?> 
<!DOCTYPE XMI SYSTEM "uml.dtd" [
	<!ELEMENT pp (pp.ElementName,
		pp.ElementType) >
	<!ELEMENT pp.ElementName (#PCDATA) >
	<!ELEMENT pp.ElementType (#PCDATA)>
]> 

<XMI xmi-version="1.0"> 
<XMI.header> 
<XMI.metamodel name="uml" version="1.1" /> 

</XMI.header> 
<XMI.content>
