Sorry, I should have also mentioned that a DTD (document type 
definition) does *not* contain a DOCTYPE (document type declaration).

You've quoted an entire document type declaration, which is not valid 
as a standalone DTD (and never has been valid as a standalone DTD 
even though a prominent vendor supported it as such in both SGML and 
XML tools, much to the consternation of other vendors who were being 
told by customers they were wrong).

Perhaps your DTDinst you are using just needs to see a DTD and not a 
document type declaration (I am not familiar with the tool):

<!ELEMENT note (to,from,heading,body)>
<!ELEMENT heading (#PCDATA)>

For example, this is the output from Trang on the above:

T:\ftemp>copy con paul.dtd
<!ELEMENT note (to,from,heading,body)>
<!ELEMENT heading (#PCDATA)>

         1 file(s) copied.

T:\ftemp>trang -I dtd -O xsd paul.dtd con
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
   <xs:element name="note">
         <xs:element ref="to"/>
         <xs:element ref="from"/>
         <xs:element ref="heading"/>
         <xs:element ref="body"/>
   <xs:element name="to" type="xs:string"/>
   <xs:element name="from" type="xs:string"/>
   <xs:element name="heading" type="xs:string"/>
   <xs:element name="body" type="xs:string"/>


I hope this helps.
