Question about binary resources: metadata/representation distinction

Hi,

I have to questions about binary resources:
- May the server support PUT to create new binary resources?
- The sepc explicitely allows POSTS of binary resources, how that the
server distinguish between binary resources and LDPR? E.g. how does it
knows if the intention is to upload an HTML file with RDFa, a textbook
example of a Turtle document where the comments are relevant or maybe if
the client want to upload the triples but the server doesn't support this
serialization format. In other words how does LDP addresses the
metadata/representation issue that URIQA[1] addresses with the MPUT HTTP
method?

Cheers,
