I really have a problem with this proposal.
The W3C seems to clearly be in the business of developing a base recommendation
and then creating profiles (subsets) of that base for specific application. I
don't see XHTML-Print to be any different from that. For example, a quick scan
of the W3C site finds:
CSS Mobile Profile 1.0 (http://www.w3.org/TR/css-mobile/)
CSS TV Profile 1.0 (http://www.w3.org/TR/css-tv)
An XHTML + MathML + SVG Profile (http://www.w3.org/TR/XHTMLplusMathMLplusSVG/)
XHTML+SMIL Profile (http://www.w3.org/TR/XHTMLplusSMIL/)
XHTML+Voice Profile 1.0(http://www.w3.org/TR/xhtml+voice/)
All these profiles are based upon the base documents (XHTMLMOD or CSS). Why
should XHTML-Print be any different? Maybe we should call this:
XHTML-Print: An XTHML + CSS Profile
Adding the complexity of using XHTML Basic (built upon XHTMLMOD which is built
on XHTML which is built off HTML4.0) and then building on top is really an extra
step and forces implementors to reference more and more documents before being
able to implement.
Additionally, CSS Mobile is NOT an appropriate starting point for CSS because it
both omits support that we need (e.g., @page, page-break-after, etc.) and
includes things we don't want to mandate (e.g., MUST support the "handheld"
media type). It would be much clearer and cleaner to simply list the properties
and property values in the same way that CSS Mobile does.
On the subject of image rotation, I have a real problem changing HTML/XHTML to
add rotation as an attribute to <img> or <src> without endorsement by the W3C.
The same issue applies to adding it to CSS.
I think what we have today which defines the base elements and base style and
then adds the additional style necessary for "Enhanced Layout" is very clean.
If we have to added to the XHTML or the CSS to accomplish image rotation then we
can.

Subject: XP> New XHTML-Print Version
Please find attached an initial proposal draft that is intended to follow up on
the presentation I gave at the last meeting.
Although the draft is not yet complete, the document structure and the partial
content should provide adequate insight into what Canon proposes as a change to
the existing specification. A more complete proposal is expected, but I thought
it was important to give an impression of our intent as soon as possible.
[My apologies that the proposal was not published in XHTML format.]
To summarize the highlights,
1) The intent is to describe X-P as a composition of 4 components:
base element
base style
additional style
image rotation
2) Only the "additional (CSS) styles" are listed in the document.
The minimum requirement for "base element" and "base style"
are references to XHTML Basic and CSS Mobile.
3) We are open to referencing an alternative "base" CSS that the group
feels is more suited for printing, if it seems appropriate
(i.e., CSS-Print could be referenced instead of Mobile.) The major
goal is modularization and reference to W3C-based standards.
