Drummond,

Thanks for the catch. 

I agree with 2, but for 1, doesn't the Ref always contain at least one
segment (thus making my wording correct)?

Let me know and I will make the change(s) to the doc.

~ Steve

Steve, good stuff. Two minor items I noted in reviewing it:

1) You say, "a no-type subsegment may only appear at the start of a
segment". Actually, it can also appear at the start of a "Ref" (a
parenthetical subsegment).

2) In your 2.1 diagram, you show *b as the first subsegment in the Ref, but
the Ref itself is of type *, and the first subsegment inside the Ref is just
"b" (an example of #1 above).

Drummond and I had a good meeting on Friday discussing 2.1 and 2.0 abstract
syntaxes.

I've posted a diagram that provides an instance diagram of the abstract
syntax tree for 2.1 (at least what we agree it to be) and compares it to
the existing 2.0 abstract syntax.

Please let us know if you don't agree. (And you let me know Drummond, if I
got anything wrong.)

The document named xri-abstract-syntax-tree-instance-diagram-v4.pdf has
been submitted by Steven Churchill to the OASIS Extensible Resource
Identifier (XRI) TC document repository.

Document Description:
This document uses a graph instance diagram
the proposed XRI 2.1 abstract syntax and to compare
syntax.
The abstract syntax represents the data structure
important example client is the XRI Resolver program.
The instance diagram approach helps to visualize
into the data structure. (It does not try to replace
formalizing the abstract syntax.)
