problem with IE5

[Betty L. Harvey]

This was my original test file:

<?xml version="1.0"?>
<?xml-stylesheet href="rep-xml.css" type="text/css"?>
<!DOCTYPE test [
<!NOTATION gif SYSTEM "gif">
<!ENTITY ecc SYSTEM "../graphics/ecclogo.gif" NDATA gif>
<!ELEMENT test (html:img, picture, para)>
<!ATTLIST test
          xmlns:html CDATA #FIXED "http://www.w3.org/TR/REC-html40">
<!ELEMENT html:img EMPTY>
<!ATTLIST html:img
          src CDATA #REQUIRED>
<!ELEMENT picture EMPTY>
<!ATTLIST picture
          name ENTITY #REQUIRED>
<!ELEMENT para (#PCDATA)>
]>
<test  xmlns:html="http://www.w3.org/TR/REC-html40">
        <html:img src="../graphics/ecclogo.gif"/>
        <picture name="ecc"/>
        <para>This is a test</para>
</test>                                    

It complains that the HTML namespace has not been declared.  The
namespace specification doesn't say anything about how the namespace
should be declared within the DTD.   

It seems to me that requiring namespaces is going to cause
havoc in implementation and conformance.
