for a primer on namespaces. This is a press release that describes why namespaces were developed for XML and what they are intended to do.
It contains this link:
Which outlines the purpose and definition of a namespace:
[Definition:] An XML namespace is a collection of names, identified by a URI reference [RFC2396], which are used in XML documents as element types and attribute names. XML namespaces differ from the "namespaces" conventionally used in computing disciplines in that the XML version has internal structure and is not, mathematically speaking, a set. These issues are discussed in "A. The Internal Structure of XML Namespaces".
URI references which identify namespaces are considered identical when they are exactly the same character-for-character. Note that URI references which are not identical in this sense may in fact be functionally equivalent. Examples include URI references which differ only in case, or which are in external entities which have different effective base URIs.
Check the more recent papers on XML to get up to speed on the changes, these articles are from 99.
Hope that helps.
