I have just started to work with XML and I am beginning to look at validation with DTDs and XML Schemas. I think I have grasped the need for and usage of namespaces within XML however, I am stumbling over the use of prefixes. For example, company A decides to create their own vocabulary using the URI www.companyA.co.uk/transaction/2003/version1 and rather than using this as the default namespace they prefix all their elements with trans. A few months down the line and a vast number of documents later they come across a vocabulary they wish to include within their own. However, this vocabulary also uses the namespace prefix trans. Even though the URIs are distinct the prefixes are the same. Does this cause problems when validating the XML i.e. the prefixes are identical and a prefix can only be associated with one URI at a time? Do they now need to change their prefix from trans to transcompanyA in all their XML? or more likely I am missing something when it comes to validating XML which uses namespaces? Apologies if this question has an obvious answer, but it has been rattling around in my mind for some time.
