Do not preserve markup of elements with the property attribute and without markup preserving datatype

[csarven]

Elements with the property attribute and without the datatype attribute, datatype="", datatype="rdf:HTML", or datatype="rdf:XMLLiteral" should not have the parser preserve the markup in the content of the element and add all namespaces and prefixes.

For example, given input:

<dd about="#foo" property="skos:definition">foo <em>bar</em> baz</dd>

the following is given:

<#foo> skos:definition "foo <em xmlns=\"http://www.w3.org/1999/xhtml\".......\">bar</em> baz" .

but the expected RDF is:

<#foo> skos:definition "foo bar baz" .

It's been a while since I looked into the processing model of RDFa.
But do you mean that the markup should not be preserved without the datatype attribute or datatype="", but it must be preserved when using datatype="rdf:HTML" or datatype="rdf:XMLLiteral"?

[csarven]

That's right AFAICT.

Doublechecking.. Some cases appear to give the expected output but some others do not, i.e., markup is preserved. For example, see https://solidproject.org/ED/protocol 's skos:definition values.
