Bad choice of wording really as the processor _has_ to use "document 
order" for attribute nodes, just as for any other node. That is a 
defined term in the relevant specifications.

It is not (in the case of attributes) necessarily the same as the order 
that the attribute markup appears in the document (if there was a 
document that was parsed to produce the XDM tree, which is not 
necessarily the case).

Whether the document markup order is preserved tends to depend on the 
parser being used rather that the xslt processor. Some parsers implement 
things by putting attributes into a hash table or similar structure 
associated with the start tag and if they do that then order isn't 
preserved.
