mistermboy has just created a new issue for https://github.com/shexSpec/shex:

== [Validating RDF Data] Example 44 : Product's status must start with... ==
This is the example 44 of the [Validating RDF Data book](https://book.validatingrdf.com/bookHtml010.html):

```
prefix codes: <http://example.codes/>  

:Product {   
      :status [ codes:good.~ codes:bad.~ ] 
}
```

I was looking at the grammars and I think that none of them allows you to do that inside a "valueSetValue":


[Master   branch grammar](https://github.com/shexSpec/grammar/blob/master/bnf) and [Shex2.1 branch grammar](https://github.com/shexSpec/grammar/blob/shex2.1/bnf)
```
[47]    valueSetValue      ::= iriRange | literal
[48]    iriRange           ::= iri ('~' exclusion*)? | '.' exclusion+
[49]    exclusion          ::= '-' iri '~'?
```

[Shex.io grammar](http://shex.io/shex-semantics/#shexc)
```
[49] valueSetValue ::=  iriRange | literalRange | languageRange | exclusion+


[50] exclusion  ::=  '-' (iri  | literal | LANGTAG) '~'?
[51] iriRange  ::=  iri ('~' exclusion*)?

[53] literalRange ::=  literal ('~' literalExclusion*)?
[54] literalExclusion ::=  '-' literal '~'?

[55] languageRange ::= LANGTAG ('~' languageExclusion*)? | '@' '~' languageExclusion*
[56] languageExclusion  ::=  '-' LANGTAG '~'?
```
