Steps to Reproduce Behavior

Paste the following code in a new text document, and save the file as Repro.dtd:

<!ELEMENT root (tag)>
<!ELEMENT tag EMPTY>
<!ATTLIST tag
attr1 (value11|value12) "value11"
attr2 (value21|value22) "value22"
>

Paste the following text in another new document, and save the file as Repro.xml in the same location as the DTD file you just created:
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE root SYSTEM "repro.dtd" > <root> <tag attr2="value21"/> </root>
Using Microsoft Internet Explorer, browse to Repro.xml.

The following is the expected result:

<?xml version="1.0" encoding="ISO-8859-1" ?> 
  <!DOCTYPE root (View Source for full doctype...)> 
- <root>
  <tag attr2="value21" attr1="value11" /> 
  </root>

However, the actual result is as follows:

<?xml version="1.0" encoding="ISO-8859-1" ?> 
  <!DOCTYPE root (View Source for full doctype...)> 
- <root>
  <tag attr2="value21" attr1="value11" attr2="value22" /> 
  </root>
