Thanks Daniel, maybe this thread will work.

My apologies, I wrote xml:id when I means xml:base in the original post.

I can see that xml:base is applied to an element in the normal way. The 
W3C Recommendation has this example:
<doc xml:base="http://example.org/today/";
     xmlns:xlink="http://www.w3.org/1999/xlink";>

It makes sense that remove all attributes should remove that one. Or at 
least have the option of removing it.

However, xml:space only seems to appear in the DTD, within an 
<!ATTLIST>. Does that just end up adding a normal attribute named 
xml:space on every affected element, but it does it "behind the scenes"?

If I wanted to change my code to preserve xml:space and xml:base, would 
I just do a string compare of "xml" to xmlAttribute.prefix and,  either 
"base" or "space" to xmlAttribute.name?

Thanks,
Rush
