low memory & WebID?

Hi,
I think WebID should be flexible enough to be used on low memory
embedded systems, does this put any restrictions on the mandated
syntaxes? I figure turtle because of prefixes would be no go, and other
syntaxes too - the algorithm for webid validation (client code),
including the parsers for all required syntaxes, would be best to have
constant space complexity...
I don't think such concerns nor the use case are so outlandish they
shouldn't be taken in consideration.

Best,
Jiri
