RE: Is order in XML guaranteed?


xml list order
There is a widely held consensus in XML that element order is significant
but attribute order is not. I don't think this is explicitly stated in the
XML Recommendation itself, but it is certainly explicit in the Infoset, and
no parser would survive in the market without respecting this.

Remember that XML was originally designed for documents. The assumption that
the order of paragraphs in a text is significant is so deeply engrained that
no-one thought it needed saying.
