By a good Conformance Statement, I meant more than
that.
I meant it in the context of ISO 9646 and concepts
of Protocol Implementation Conformance Statement
(PICS) Proforma and PICS.
To evaluate conformance of a particular
implementation, it is necessary to have a
statement of the capabilities and options that
have been implemented for a given protocol (and
bidi can reasonably be regarded a protocol, as it
is based on expected behavior). Such
a statement is called a Protocol Implementation
Conformance Statement (PICS).
I don't know if there is a PICS-Proforma for
http://unicode.org/reports/tr9/.
If there was, it would take the form of tables
refering to the base spec asking for details of
implementation with regard to each
section/option/feature/... of the specification.
An example of PICS-Proforma in the RFC Series is:
http://tools.ietf.org/html/rfc1708
Pics is taken more seriously in the ISO/IEC
ITU/CCITT cultures. Various people have various
opinions on merits of the PICS model. I like the
PICS model and have managed to put it to good use
in realization of large networks.
In the absence of a PICS-Proforma, based on your
implementation details, you (or somebody) can go
through the specification and include emacs-bidi
implementation details and cross-referencing UAX#9
sections.
Given the lack of precision for uniformity in
determination of say paragraph direction, based on
the emacs PICS, we can then visit our sisters at
Mozilla and have a conversation towards more
harmony.
