Exclusion of NONE and NOASSERTION from ABNF
Terin Stock <terinjokes@...>
The ABNF in Appendix IV of the 2.0 version of the specification allows for short form identifiers, LicenseRef values or combinations to form a license-expression. However the values "NONE" and "NOASSERTION" are not valid in a license expression, despite their useful and defined meaning in the specification.
Are these two values excluded from the ABNF on purpose?
