long term webid of peter, contrary to rumour

at yorkporc.wordpress.com ive hosted on the blog's front page the site's contact page (from wordpress.com). It has in HTML the kind of information normally shown in a foaf card. it has my long term webid, hosted on an opera unite endpoint. Its not a foaf card like others and neither is the endpoint (being only available when I am online).  I happen to enforce more privacy than perhaps do most consumers (being a security type engineer who is experimenting with semantic web ideas, as they evolve). I know some folks want foaf cards as public data, cacheable by search engines and others maintaining huge triple stores. I dont. I want to assert my privacy expectations (becuase in the US, one has no rights until they are asserted - this being the way that social laws on privacy happen to be structured.) And I do this in ways that may not meet the idealized, academically-normalized semantic web concept, which assumes you have public documents that anyone can browse, cache, cite from, etc. Now  does anyone know HOW to make a wordpress contact page embed either (1) an XML stream, coding up the xml-serializion of a foaf card (e.g. the output of foaf.me), or(2) the RDFa of a foaf card. I cannot make either work. I seem to remember that one was supposed to be able to add  "XML data island" as a subelement in HTML (since XHTML is just an XML vocab). One is supposed to be able to embed RDFa tags in HTML elements too. Unfortunately, the wordpress site strips out what I add (refusing to host them). Ill guess that these are default safety options, that can be removed by those who know how. My wordpress blogsite is hosted by wordpress cloud service, not by me on a server (im not sufficient competent to run a production server). So, there may be less ability to change the configuration to offer RDFa and XML embedding, than a site one hosts on a private server.
