yes and no. A subset of RDFa is usable with GRDDL.
The full power of [RDFa][1] is only possible *for now* in XHTML 2.0.
For example, Litteral properties
[[[
<h1>Photo Album #12345: <span property="dc:title">Vacation in
the South of France</span></h1>
<h2>created by <span property="dc:creator">Mark Birbeck</span></h2>
]]] -- RDFa Primer 1.0

The attribute property is only available in XHTML 2.0, not XHTML
1.* family.
*BUT*
The profile attribute is not part anymore of the [XHTML 2.0 list
of attributes][2].
*AND*
GRDDL requests to have a profile attribute in the head.
[[[
A reference to http://www.w3.org/2003/g/data-view
from the profile attribute (c.f. section 7.4.4.3
Meta data profiles of [HTML4]) of an XHTML document[XHTML]
indicates that links of type transformation relate
the document to transformations that preserve
its meaning.]]]

Summary: (As it is defined now)
GRDDL can be used now and only with XHTML 1.0, XHTML 1.1
And only a subset of RDFa can be used with XHTML 1.0, XHTML 1.1
And GRDDL is NOT usable on XHTML 2.0
The issue has been raised in HTML WG
[[[
It is not possible to define anymore new value
for "class" in a defined way, because the profile
attribute has been removed in the benefit of meta.
]]] - [property value limited to one value][3]
