RE: css3-fonts: should not dictate usage policy with respect to origin

This situation is similar in many ways to that of XPath in the XML
specification: XPath doesn't stand alone, because XPath is an embedded
language, but we can't put constraints on the language that embeds
XPath.

So, we put constraints on the way in which XPath is used when embedded.

What might this mean for WOFF?

The WOFF spec could say in its conformance section (right in the spec,
not in a separate document) that for use in style sheets (not only CSS)
an implementation-defined mechanism should (must?) be available to limit
access to the WOFF resource outside of support for the style sheets, and
maybe give same-origin as an example.

(It would also presumably also say in tta section that WOFF fonts are
not intended to be used directly for document and style-sheet creation,
but are instead a delivery format).

Then a Web browser, or an SVG renderer, or an XSL-based typesetting
system, in order to claim support for WOFF, would need to document the
particular mechanism that they supported; CSS, XSL, SVG, HTML would not
need to say anything specific.
