Has PCL-XL been left out intentionally?

There're PCL-XL 1.1, 2.0, 3.0, etc. Microsoft GPD based mini drivers is
able to generate PCL-XL.

Hi George,

Right - we're only talking about the graphics drawing aspect
of these printer languages.

The IEEE 1284 Device ID format only supports a list of
printer languages - it cannot be extended (interoperably)
for these other device-specific aspects.

The PWG cannot actually extend the capabilities keywords
or their syntax in the base IEEE 1284 spec.

So the scope of comments we're requesting is only to identify
any other common variants of PCL (for example) that should
be registered with IANA.

All of these are enumerated values in the single Printer MIB
integer object prtInterpreterLangFamily.  Other objects such
as prtInterpreterLangLevel and prtInterpreterDescription can
be used by vendors to distinguish vendor-unique features.

Cheers,
- Ira
