I don't know what you are doing because it works 'fine' for me even with
DTD validation and entity substitution:

paphio:~/XML -> xmllint --valid --noent tst.xml
tst.xml:10: element widget: validity error : No declaration for
attribute xmlns:xyz of element widget
<xyz:widget xmlns:xyz="&widgets-ns;">
                                    ^
tst.xml:11: element content: validity error : No declaration for
attribute src of element content
  <xyz:content src="&pass;"/>
                           ^
tst.xml:11: element content: validity error : No declaration for element
content
  <xyz:content src="&pass;"/>
                             ^
tst.xml:12: element name: validity error : No declaration for element
name
  <xyz:name>bv</xyz:name>
                         ^
tst.xml:13: element widget: validity error : No declaration for element
widget
</xyz:widget>
             ^
<?xml version="1.0" standalone="yes"?>
<!--
     Tests support of XML, XMLNS, and UTF-8. To pass, the user agent
must load
     pass.html.
     -->
<!DOCTYPE widget [
<!ENTITY widgets-ns "http://www.w3.org/ns/widgets";>
<!ENTITY pass "pass&amp;.html">
]>
<xyz:widget xmlns:xyz="http://www.w3.org/ns/widgets";>
  <xyz:content src="pass&amp;.html"/>
  <xyz:name>bv</xyz:name>
</xyz:widget>
paphio:~/XML -> cat .memdump 
      02:23:21 PM

      MEMORY ALLOCATED : 0, MAX was 31209
BLOCK  NUMBER   SIZE  TYPE
paphio:~/XML -> 

 and the parser allocated only 31 KBytes to build the document.
