7835 - What should html:linked stylesheets do in XML

Status: VERIFIED DUPLICATE of bug 7516

(Core :: CSS Parsing and Computation, defect, P3)

Description

[David Baron :dbaron: (⌚️UTC-5, no longer working on Mozilla)]

What should a stylesheet linked through the {html namespace}link element do in
an XML document?  I think it should definitely do something in a document that
is simply HTML converted to XML, i.e., where the root element is the {html
namespace}html element, such as the one above, with the stylesheet-linking PI
removed.  (But maybe not - Maybe you want to encourage the PI.)

However, one solution would be to apply the stylesheet from the link element
only to elements within the HTML namespace - that is, it would be a stylesheet
linked only to the html namespace.  Some CSS3 concept of interaction between
namespaces and stylesheets would probably be useful here, so WG opinion, which
you know and I don't, is probably the way to go.

To the best of my knowledge, the XML folks (and the XHTML folks) are really
wanting PIs to be used instead of application specific link tags. Doing this may
not be expressly forbidden (yet), but it would likely piss them off.

In all likelyhood, <html:link> tags will be forbidden from XHTML so this is
moot. Rick, any word from the XHTML front on this?

If we do support <html:link>, I like the idea of constraining the linked sheet
to HTML namespaced markup.

PIs map directly to <html:link>, as do HTTP 'Link' headers (whether real or
implied by META tags).

I suggest the lot be implemented generically, and further suggest that they
all work for everything. Why ban things when it is as easy to implement it
the complete way?
