I can't answer the question directly about MochiTAL, but when I saw
MochiTAL more than a year ago I decided to write a more complete
implementation of TAL in javascript called jstal.
I have combined jstal with an XSLT implementation (tal2xslt) into a
single package ATALi (Alternate TAL Implementations) which you can
find at https://launchpad.net/atali
(apache license)
Hmm, there's no docs and no examples, so this post is probably wasting
your time.
I use both jstal and tal2xslt every day in production. I really need
to finish this project up.
Is anyone interested?
The one thing that is holding me up is lack of tests. I need a good
xml diff tool so I can write tests for tal2xslt, and I would need
something similar for jstal in javascript. (rhino?)
