Re: [ba-ohs-talk] ANN: GSIX, v0.44.

Murray,    (01)

I've had a _quick_ glance at GXL.    (02)

There's a lot of semantics in the markup. I prefer options if possible.    (03)

GXL question:
What's the point of chaining attr?
<!ELEMENT attr (type?, attr*, (%val;)) >
That's like having a separate tree spawning off everthing. Why is that
information captured in that way and not just as part of the graph?    (04)

Otherwise, as far as I can tell in a hurry, the rest of the graph is just
like the basic statement of GSIX without the power of contexts, but maybe
I'm missing something.
Have you managed to engineer contexts in GXL?    (05)
