Hi all,

Thanks to all who reviewed.  The presentation has been updated.  Detailed comments below.

Thanks, normalized.

OK.  Changed.

In general, there was an attempt to allow as many characters as possible unescaped in prefixed names (period, colon, digit at start), while allowing the rest in escaped form.

Looking back at the presentation and my notes, I have no idea why that is there.  It has been removed.

Thanks to Nathan, Dan and Andy for catching that error!

Hmm, no.  I didn't want to say anything about anything that might not happen.

Good catch!  The January 2010 ED [1] says "case-independent constants for XSD booleans true and false", but the current Turtle editors' draft, section 3.2.3 [2] says:
Boolean values may be written as either true or false (case-sensitive) and represent RDF literals with the datatype xsd:boolean

Thanks, added.

Thanks.  I added the word "mutable".
