[sword-devel] morphcode: specification, and frontend usage ?

[Troy A. Griffitts]

A quick comment:

OSIS w attributes are space separated lists and thus spaces should be
avoided within the codes and where spaces absolutely must be included,
the spaces within the data need to be escaped.  We did some research
into how other projects escape space separated XML lists and didn't find
anything official so we a bit about which character we should use, but
never really decided.  I think what we did decide was to simply not use
codes with spaces, for now, thus the - between code segment.  If the
current Packard lexicon uses spaces instead of dashes, then I would say
the lexicon needs to be updated to match our decision to use - in the
modules.  I think we talked about supporting a  + or _ as a space
escape, but just looked at the osis filter and don't see any code to
handle an escape code.
