The following realization proposal builds on adding an abstract class as an intermediate layer. Consider the following descibed steps, shown also graphically in the image attached. In addition a sample implementation is available in the attached package.

a) Abstract class is introduced to define all attributes necessary for the sub-class.
b) E has aRx and bR‘y, so it can be modelled. As bRy is semantically not the same as bR‘y, queries need to consider both (e.g. a union of bRy and bR‘y)

Sample Realisation of solution 2b - Version 2: as attachment to this post

a) Abstract class is introduced to define all attributes necessary for the sub-class.
b) New additional pointer is introduced.
c) E has aPx, bPy and ePy, so it can be modelled as pointer and can be queried by pointer name. For visual represenation of the pointer, additional drawing of generic relation is necessary. As pointers are instance attributes, the search needs to consider the query of instance attributes.
