Ability to add optional elements in an asset view's shape

Currently when building an asset view's shape, the matches received would only cover the elements that are found in the PI AF database that match that shape.

It would be good to have an option where if a child element is considered optional in the shape, matches would also be returned for elements In the AF database which do not have that child element.

An example of this would be:

If an Asset view is being built on the integrator where the following shape is introduced:

Site

EQ1

EQ2

Site, EQ1 and EQ2 are all element templates which exist on the same AF database.

In the underlying AF hierarchy, not all Sites have both EQ1 and EQ2 as child elements, some sites have EQ1 only and some other sites have EQ2

When this shape is applied on the asset view, only the Site elements which have both EQ1 and EQ2 are found.

It would be good to have a way to make the view also find Site elements which contain either EQ1 or EQ2.
