Not that I can think of.  But consider the presence of a DTD: what *is* the 
original order?

<!DOCTYPE sample [
<!ELEMENT sample EMPTY>
<!ATTLIST sample
           att1 CDATA "blort"
           att2 CDATA #IMPLIED
           att3 CDATA #REQUIRED>
]>
<sample att3="wibble"/>

What is the order of attributes?  Very good cases can be made for either 
3,1 or 1,3.

Now consider the case of a well-formed document with some attribute 
defaults declared, but other attributes just given in the instance.  What's 
the order there?
