Order of XML attributes

The order of attributes within an XML tag are of no significance. For instance, the two XML snippets below are functionally equivalent, even though, in the first example the xs:schemaLocation  is located in the middle of the tag and in the second example xs:schemaLocation is the last element of the tag.

Please see examples below:

<?xml version="1.0" encoding="UTF-8"?>
<ern:NewReleaseMessage xmlns:ern="http://ddex.net/xml/ern/35" 
                       xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
                       xs:schemaLocation="http://ddex.net/xml/ern/35 http://ddex.net/xml/ern/35/release-notification.xsd" 
                       MessageSchemaVersionId="ern/35" 
                       LanguageAndScriptCode="en">

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ern:NewReleaseMessage xmlns:ern="http://ddex.net/xml/ern/35" 
                       xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" 
                       LanguageAndScriptCode="en"
                       MessageSchemaVersionId="ern/35" 
                       xs:schemaLocation="http://ddex.net/xml/ern/35 http://ddex.net/xml/ern/35/release-notification.xsd">
