In XML, is order important?

Question

Is the order that elements of a common parent appear in XML a meaningful piece of data captured by the XML document, or is order not specified as being meaningful? For examp

Answer 1

According to this article, the 1.0 version of the standard doesn't even require that parsers report siblings in the order they appear in the document. In that light, they would not be considered different, as both children are there. Perhaps this has changed, so that other answers are for newer versions of XML, though.
