Why doesn the XML namespace associated with the CPE Dictionary and CPE Language change between minor versions?
This is a long standing discussion with no real right or wrong. We have always chosen to keep the namespace the same for minor version so as not to force existing content to change. If we changed the namespace, then all existing content would have to be modified to relate to this new namespace, even though the rest of the XML document might not have changed. Also, the argument can be made that we are not changing the meaning of the elements in the schema, rather we are just modifying the child elements and attributes. Without a change in meaning, the namespace should not change, that way tools that are importing instance documents can continue to “understand” the xml. In other words, a ‘cpe-list’ element still means the same thing, and a ‘title’ element still means the same thing.
