Predicate to check if a value is either true or false.

The single arity version returns a predicate that checks
if all x in xs comply to the predicate.
The 2-arity version returns a predicate that checks if all
keys and all values comply to key-pred and val-pred, respectively.

Creates a multimethod for the metamodel that provides defaults from
the given map.

Defines several vars in the current namespace:
- The sym-hierarchy var contains the type hierarchy.
- The sym-metamodel var contains a map with keys/values :hierarchy and :types.
- For each type a factory function that creates and checks a model element for that type.

Returns the docstring for a model element factory function.
Needs to be public to be available to code genererated by macro.

Merges attribute maps to implement field inheritance for the type
specified by `type-keyword`.
Needs to be public to be available to code genererated by macro.

Returns a factory function that is used to create model elements of the
type described by type-keyword and attrmap.
Needs to be public to be available to code genererated by macro.

Returns the type-keyword of the model-element me.

Returns true if me is of the meta-type specified by type-keyword.

Returns a readable representation of the model element as Clojure data.

Returns a predicate that checks if x is of the metatype specified
by type-keyword.

Returns a predicate that checks if a given value is contained in
the set of keys.
