Does the order of xmlns elements matter

I'm not sure how to search google for this but does the matter of the xmlns elements matter in an XML File? I'm creating a XML file using XMLWriter in ASP.NET(VB) and I'm trying to match an example I was provided. 

<ns2:SubmitSMReq xmlns:ns4="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns3="http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-6-MM7-1-4" xmlns:ns2="http://somesite/schema">

This is what I have in my vb file:

writer.WriteStartElement("ns2", "SubmitSMReq", "http://schemas.xmlsoap.org/soap/envelope/")
writer.WriteAttributeString("xmlns", "ns3", Nothing, "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-6-MM7-1-4")
writer.WriteAttributeString("xmlns", "ns4", Nothing, "http://somesite/schema")

But it generates the XML differently. 

<ns2:SubmitSMReq xmlns:ns3="http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-6-MM7-1-4" xmlns:ns4="http://somesite/schema" xmlns:ns2="http://schemas.xmlsoap.org/soap/envelope/">

I realize the xmlns in the provided example has different "ns" (namespace?)" numbers. Does either of these things matter? Should I be alright with my file?

Thanks

According to the current version of the XML specification,

the order of attribute specifications in a start-tag or empty-element tag is not significant.

So no, it shouldn't matter, assuming that the system which eventually reads your XML is compliant.
