  /**
   * 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.
