Question:

What is XML Namespaces?

Answer:

Provide a way for preventing tags with same names & different meanings from conflicting. 

Has the form: <html xmlns = "http://www.w3.org" >
Doesn't actually use the URLs

You must declare a namespace with a prefix; the XML namespace without colons and a prefix is the default namespace (in the case below, HTML):

<table xmlns="http://www.w3.org" xmlns:furn="http://www.furniture.org/tables" >
<tr><td><furn:table sku="12312">Table</td></tr>
<tr><td><furn:type>Coffee Table</td></tr>
