Hi Mike,

My ABNF is pretty rusty, but it seems that these enhancements don’t resolve the issues I was discussing with the PWG in earlier email threads to the reflector (“JPS3 “printer-output-tray” - supporting additional optional keywords from”).  We discussed fixing the ABNF to allow arbitrary keys to be allowable by the ABNF for “printer-output-tray”, because there were fields from prtOutputTable that we agreed should also be available or at least encodable, such as prtOutputModel.  That doesn’t seem to be a possibility with this ABNF draft or PWG 5100.13 (JPS3).

It seems like if we were going to support this and we were to limit the size of the custom key to some value (24 in this case) then we would make the following changes or something similar?

output-opt          = output-index /
                      output-unit /
                      output-stacking-order /
                      output-page-delivery /
                      output-offset-stacking /
                      custom-key

; allow a custom key to be 1-24 characters in length, composed of ASCII letters, digits, or “-“
custom-key        = 1ALPHA [*23(DIGIT / ALPHA / “-“)]

Thoughts?

Smith
