Greetings Shane, fair question. During the October face to face we 
discussed this [1] and made a resolution: 

        RESOLUTION: keep everything from XHTML 1.0 definition of script

So the question in my mind is why change from @charset to @encoding in 
        " SM: changed for XHTML2 in response to comment from i18n "

but what was their rationale? People have now become familiar with 
@charset and even our description of @encoding feels it necessary to 
mention how it relates to accept-chaset in http. Perhaps someone can 
articulate the benefit of changing and how it outweighs the disadvantages 
of change.

Issue with @charset vs. @encoding in XML Scripting Module

XML Events 2 defines the XML Scripting Module [1] - this module defines 
the script element and its required attributes.  While working with this 
module and its Schema and RelaxNG implementations, Markus and I ran into 
a quandary that I do not know how to address.

XML Events 2 has two different audiences.  There is the "today" audience 
that might need the XML Scripting Module, and the "tomorrow" audience 
that will use all the modules in languages like XHTML 2 and XForms 1.2.

Right now, the script element uses the @charset attribute as defined in 
XHTML Modularization 1.1 [2].  And that's fine.  It makes sense in a 
pre-XHTML 2 world.  However, if we are going to include XML Scripting in 
XHTML 2, we really don't want @charset.  @charset has been superseded by 

Anyway - in implementing the script element for XHTML 2 I decided that 
we really meant @encoding.  This is in conflict with the draft XML 
Events 2 spec though.

Question: Do we change XML Events 2 to use @encoding as defined in XHTML 
2, change XHTML 2 to use @charset for this one element, or develop a new 
version of the XML Scripting module in XHTML 2 that overrides the one in 
XML Events 2?
