Hi Mike
%NL; is a single character <LF>
on those target platforms where that is the convention or <CR><LF>
on others, etc. This is intended to make it easier for the same dfdl schema
to parse messages from different platforms. I know we avoided target platform
in DFDL and was expecting that this would cause some debate.
This will be a good discussion for tomorrow's
call

Is the &NL; supposed
to represent a single character? Or can it be a CRLF?
There’s no notion of
“the target platform” in DFDL. We’ve specifically avoided this notion
on purpose. So we need a separate property like newline=”&CR;&LF;”
or newline=”&LF;” if we want &NL; to be meaningful, unless some
other property is suitable.
There are some other Unicode
whitespace and Unicode line-ending characters. Do we want to include those
in the definitions of WSP and NL ? I recall there are 4 line-endings in
Unicode.

All
Attached is the latest proposal for DFDL 'entities'
The main changes are:
- No longer using XML entities as this proved to not meet all the requirements
- New generic mnemonics for <NL> and others to represent the NL on
the target platform.
