Yes it does.  I can't speak for Chris Wilson, but Anne quoted a
paragraph of the spec which alleviates my concern here.

Since you obviously understand the word 'strongly' and do not need a
lesson on what an adverb does, can you clarify the reason you do not
want to strengthen the language of this paragraph in some way?

Can you please clarify why you believe this?  If Mozilla releases a
browser next year that supports SVG-in-text/html that will be
(roughly) 20% of all web browser users on the planet that can suddenly
use the feature.  That is a 'significant deployment footprint' in my
book.

Can you further clarify why you expect people who want to edit vector
images they find inline with their HTML will know to seek out
toolchains that support SVG-in-text/html?

Here's the scenario I'm thinking about: Someone sees a picture they
like on a web page, view source, see it is inline SVG and think "Hey,
I have an editor for SVG already installed!".  They copy/paste the SVG
into a text file and open it up in Inkscape that they've had setup for
a couple years and wonder why it doesn't work.  They won't
automatically think they need to install a new tool for that (and why
should they?  It's 'SVG' after all...

Anyway, I have created a bug against Inkscape:
https://bugs.launchpad.net/inkscape/+bug/367997 - please feel free to
add details/corrections to this bug.

Ok, you think they will go to a tutorial site?  I think it's fair to
say that nearly every introductory tutorial written today also
describes SVG as a dialect of XML.

Simple to whom?  For instance, It's not immediately obvious to me why
alt=x==y shouldn't result in alt value of "x==y" (but it must be
obvious to people who have analyzed lots of HTML content and thought
this through longer than I have).
