Re: [XHTML] XML Events 2 : script element, @implements

aloha, roland!

roland asked:

Question 1: is this what the participants thought was agreed?

GJR answer 1: yes -- @implements tells the system that if there is an 
implementation of that NS, to ignore this script, or, if no script is 
present, to use the @implements to point to the pertinent namespace
URI for the markup dialect/version/module which the user agent or an 
expert handler -- a piece of middleware that provides context and the 
language's ontology -- to invoke that namespace in order to properly 
parse input and output interactions with specialized knowledge domain 
dialects, such as CellML (http://www.cellml.org/)

Question 2: if it was, then is a namespace not too coarse a unit? Should 
we identify features within a namespace, perhaps a feature might be 
equivalent to an XHTML module.

GJR answer 2: hmm. this does merit some discussion and thought -- roland,
did you have specific granularity levels in mind when you posed the 
question?

Question 3: how, if it all, does this relate to the DOM hasFeature method?

GJR answer 3: in the minutes cited in your post,

shane mccaron pointed out via IRC that:

We can also do that with an @if that checks HASFEATURE so @implements 
is then a shorthand

we originally had this discussion at my request, in regards the Open 
Accessibility Workgroup's exploration of an Expert Handler for Specialized 
Markup and Assistive Technologies

i believe that the implements attribute provides the necessary 
functionality for an expert handler to work reliably and consistently
