ISSUE-25: default datatype for literals

Issue 25:
http://www.w3.org/2006/07/SWD/track/issues/25

What should the default datatype of literals be in RDFa? We've talked
about this one fairly in depth, and we have general agreement from a
past telecon, including a nice flowchart diagram put together by
Michael [1]. In addition, there was just a recent discussion about what
the value of @datatype should be [2].

The current proposal, as it stands, is as follows (I am duplicating work
done by Michael just to freeze this in time):

==============

A) @datatype is explicitly specified.

The literal has the datatype specified. @datatype="" means a plain
literal, which @lang affects as expected.

If @datatype="" is specified and the literal contains markup, the markup
is stripped according to typical textContent rules.

B) @datatype is not explicitly specified.

  B.1) @content is specified.

  The literal is the value of @content and is a plain literal, which
@lang affects as expected.

  B.2) @content is not specified.

    B.2.a) the literal value contains markup, e.g. "<b>foobar</b>"

    The literal is of type rdf:XMLLiteral.

    B.2.b) the literal value does not contain markup

    The literal is of type plain literal, which @lang affects as expected.

==============

If this is not your understanding of what we agreed upon, or if you have
found reason to disagree with this, speak now! And if you like it, speak
now anyways, at least to say "+1."
