How should multiple definitions of sh:qualifiedValueShape of a property constraint be treated?

Description:

Hi!

The current specification does not specify how multiple sh:qualifiedValueShapes should be treated when they are used within a single property constraint.

For example, if I want to specify that there must exist exactly 3 values for ex:parent where at least 1 of them must be ex:female (and ex:male respectively), the current specification does not prohibit me from writing something like this:

ex:QualifiedValueShapeExampleShape
a sh:Shape ;
sh:property [
sh:predicate ex:parent ;
sh:minCount 3 ;
sh:maxCount 3 ;
sh:qualifiedValueShape [
sh:property [
sh:predicate ex:gender ;
sh:hasValue ex:female ;
]
] ;
sh:qualifiedMinCount 1 ;
sh:qualifiedValueShape [
sh:property [
sh:predicate ex:gender ;
sh:hasValue ex:male;
]
] ;
sh:qualifiedMinCount 1 ;
] .

Of course, one way to approach that would be to use sh:AndConstraint for >1 qualifiedValueShapes, but that's not explicitly mentioned in the draft.

btw. there is a typo in the code example of the draft ->

sh:predicate [
sh:predicate ex:gender ;
