>>>(it seems that IE does this by default)
Correct. IE uses MSXML internally. The page
http://www.PerfectXML.com/msxmlWellFormed.asp also uses MSXML to check if
the XML document is well-formed.

Yes, you're right.
Running RXP with -Ns option catches this too (it seems that IE does this by
default)
Warning: Attribute name :test has empty prefix
in unnamed entity at line 3 char 16 of file:///C:/x.xml

in unnamed entity at line 3 char 23 of file:///C:/x.xml
