/**
* get a property association from the properties section of the containing classifier if the

* of a target and a context. The context must be a NamedElement in its containing classifier,
* i.e., a feature, feature group, subcomponent. The property holder is assumed to be contained in
* the context object, e.g., a feature in afeature group or a data subcomponent in a port, or
* feature in a subcomponent. The association must match the property definition. if the context
* is null then the containing classifier of the target is used and the path must be one or no
* path. The applies to clause of the property association must be of size 2 if the context is set
* and point to the context and then the property holder. The property value of the property
* association is assumed not to be modal.
*
* @param context NamedElement whose containing classifier's properties section is searched for
* the desired property
* @param target NamedElement the model element to which the property is applied to via the
* applies to clause
