Hi, Actually it is simpler to put namespaces everywhere... You don't have to use them but this a good practice especially since with XML different documents could be combined by a third party or a partner and you cannot know what you'll have. You should see it as a maintenence/evolution things. At my past job, I created namespace for each document and then I used an XSLT to delete them before processing (I was using Cocoon so I was using pipelining). This proved to be a small overhead of treatment but useful in several cases. One last thing: you don't have to do <myNS:myTag>... you could instead declare it anonymously this would work just as well and be (or so I think) could enough.

In http://www.rpbourret.com/xml/NamespacesFAQ.htm#q5_3, it says: ...the purpose of XML namespaces is to uniquely identify element and attribute names. Unprefixed attribute names can be uniquely identified based on the element type to which they belong, so there is no need identify them further by including them in an XML namespace. In fact, the only reason for allowing attribute names to be prefixed is so that attributes defined in one XML language can be used in another XML language. This quote suggests that, when designing a schema/DTD one can safely let most (if not all) attributes have no namespace (i.e. be "unprefixed"); the designer only rarely should need to specify an attribute as belonging to a namespace (i.e. requiring a prefix). But I am interested in learning to recognize those rare situations in which, as a designer, one *should* put a particular attribute in a namespace. This is still very unclear to me. What are the requirements that an attribute must fulfill to be a good candidate for being placed in a namespace by the schema/DTD designer?
