SVG does not consider itself to own the user agent. Irrespective of 
whether an SVG document is standalone or embedded, it still requires a 
syntax in which to be expressed, otherwise how can one create content 
for it? It still needs to require the support for some formats in order 
to be interoperable, otherwise the said larger presentations would not 
represent a reliable target for content creation, etc.

I am not trying to represent you as stupid, simply to communicate to you 
what I understand from reading your message so that you would have a 
chance of clarifying your position. You claim that "If [I] reread [your] 
message later, [I] will have to admit that [you] could not possibly mean 
to remove those items in the parentheses, namely 'elements and 
attributes syntax, semantics, rendering model and specific APIs'". I 
have reread your message, and for context the relevant sentence was:

a vector graphics profile, which could be the current SVGT1.2 profile
purged of any non vector graphics item (elements and attributes syntax,
semantics, rendering model and specific APIs)

In what other way can this be understood? If your proposed profile is 
purged of the items in the parentheses, how can they not be removed?

Note that I also asked for specific details, which you don't seem to 
wish to provide.
