Hi Marcos,
Thanks for the link!
It is very helpful.
It seems, however, that the versioning battle is still there.
The blog you directed me to is still just a blog AFAIK.
Yes, but the blog post is written by an authority on the subject. See
also the posts by David Orchard, who is also a highly respected
authority on the matter. There are whole conferences on the subject too,
if you need academic sources that support the rationale for not using
versioning.
So http://www.w3.org/TR/webarch/ may need an update as in the blog, presumably
preceded by some discussion.
As a kind of summary, it is ok for me to have namespace as versioning mechanism.
Right. But not in the manner you were suggesting. Only use namespace
versioning as a last resort (i.e., the language is soooo "fubar", in the
classical sense, that a new namespace is needed ).
Having namespace + version + baseProfile seems redundant.
right.
Thanks.
Kind regards,
Marcin

I have reviewed a few recommendations from http://www.w3.org/TR/.
a) SVGT1.2 http://www.w3.org/TR/2008/REC-SVGTiny12-20081222/ says:
"Future versions of this specification will maintain backwards
compatibility with previous versions of the language" SVGT1.2 uses
version attribute to describe the version of the standard that
was used to write the SVG document. They also use "baseProfile"
as a further means for content versioning/requirements in
http://www.w3.org/TR/2008/REC-SVGTiny12-20081222/single-page.html#implnote-VersionControl.
Just to be clear, version="" and baseProfile="" in SVG Tiny 1.2 are used
only as a hint from the content author as to what minimum version of the
language is required for the content to work properly. No difference
in processing is required for differently specified version="" and
baseProfile="" attributes.
See also the link below for a detailed discussion as to why you are
suggesting in not ideal:
