In ShEx 2.0, the productions were defined as follows:
[49] valueSetValue ::= iriRange | literalRange | languageRange | '.' exclusion+
[50] exclusion ::= '-' (iri | literal | LANGTAG) '~'?
In ShEx 2.1, they were updated to the following:
[49] valueSetValue ::= iriRange | literalRange | languageRange | exclusion+
[50] exclusion ::= '.' '-' (iri | literal | LANGTAG) '~’?
But, the note on [49] still notes "If "." matches and exclusion matches one or more times”, and that doesn’t make sense in this context. Also, the third ValuesConstraint example has a ‘.’ only at the beginning:
ex:EmployeeShape {
foaf:mbox [ . - <mailto:engineering->~ - <mailto:sales->~ ]
}
Looks like the changes were made in error? Certainly, the new grammar is not forward-compatible with 2.0.
