Why only "Canonical XML"? 
http://www.w3.org/TR/rdf-concepts/#dfn-rdf-XMLLiteral requires 
*Exclusive* Canonical XML (specifically "encoding as UTF-8 [RFC 2279] 
yields exclusive Canonical XML (with comments, with empty 
InclusiveNamespaces PrefixList ) [XML-XC14N]"), referencing 

I expect this errata (and future versions of the RDFa Syntax 
Recommendation) should therefore refer to xml-exc-c14n instead of 
xml-c14n (unless the intent is a willful violation of rdf-concepts, or 
unless rdf-concepts is changed before then).
