Thanks. I managed to made some changes to wiki in parallel.
Unfortunately, I will not be able to attend the call tomorrow and the
rest of the week afterwards.  One goes inline.

I believe Boris is main supporter of  infinity of characters, and he
has explained the reason in a couple of discussions and emails. I have
removed the EdNote (before seeing your mail) as in the last telcon
there is no objection for its removal. If there will be a vote on this
tmr, my cast would be "0".

It helps, I will try to come up with an example

i have made a Note

Note: In addition to language tags, RDF applications may use
additional mechanisms for internationalized text, such the use of
"xml:lang" in literals of the type "rdf:XMLLiteral". rdf:text does not
provide a replacement to these mechanisms.

I have made a note

Note: The abbreviation of "text"^^xs:string as "text" follows from RDF
entailment rules xsd1a and xsd1b [RDF Semantics].

This makes it clear that abbreviation does not result in syntactical
equivalency (so maintains the backward compatibility with RDF)
