Please don't put words in my mouth. I just said I understand Linked Data
and how it works. In fact I believe it is very good thing and have been
encouraging it's use for some time.

No, I believe in negotiated representation, but I respect people who
want lightweight implementations which support only the bare minimum and
I am willing to support them as well. You on the other hand seem to
believe solely in negotiated representation, regardless if its
disadvantages, which of course exist as any purposeful thing in the

I am familiar with XDR and its usage in RPC.

Like I said, you are misunderstanding me, thinking I mean things I
I am just willing to support more people with different points of view
who generally don't understand our Linked Data / Semantic Web
perspective, sacrificing idealistic purity for a practical solution.
