HTML fragments in content constructs


It is a very common use-case that HTML content in an Atom entry will
be embedded amongst some other HTML and a bunch of other Atom entries.

So is there any restriction on the type of HTML tags that are allowed
in a content construct?

It is usual for entry content to be labeled as @type="text/html", but
really contain HTML fragments - not full HTML.


Should both of these be allowed:

a)

<atom:content mode="xml" type="application/xhtml+xml">
some <b>mixed</b> content
</atom:content>


b)

<atom:content mode="xml" type="application/xhtml+xml">
<html>
<head><title>Title</title></head>
<body><p>A complete file</p></body>
</html>
</atom:content>


Should we define what is expected in terms of the XHTML DTD [1] so
that people know how to frame the content - Eg: %Flow or %Block or
%Inline ?

Or is this out of our scope?


A few possible proposals:

  i) Just add a note to the spec to say that content constructs MAY
     contain fragments of the media type that they are declared to
     contain.

 ii) Say that HTML content SHOULD comply to a particular element set
     such as %Flow

iii) Add an attribute such as @framing="full|fragment" to the content
     construct.

or all of the above?
