Minor version not included in namespace #24

I noticed that the minor version is not included in the namespace, i.e. 1.0 and 1.1 share the same namespace (http://www.fdsn.org/xml/station/1 -- with full version included as an attribute version="1.1") and thus it's not possible to add (removed) 1.0 tags as foreign tags in 1.1 documents (e.g. StorageFormat). Any thoughts on this? I'm used to namespaces including the full version number somehow (e.g. http://geofon.gfz-potsdam.de/ns/seiscomp3-schema/0.10), but no expert on normal practice in this domain by any means.

I agree this is not the typical choice in a situation where neither documents of version 1.0 fully validate against schema 1.1, nor vice versa. (a good reading on the topic is e.g. http://www.xfront.com/Versioning.pdf ) However, I guess this should be carefully reconsidered for the migration to version 1.2 in the light of the changes planned for that revision.
