Entity Framework - Multiple Discrimination

In a Table-Per-Hierachy script, can I distinguish a list of possible values?

eg. for typesColor, DarkColor, LightColor

sort of

 Map<DarkColor>(m => m.Requires("TheColor").HasValue(Red || Blue)
 Map<LightColor>(m => m.Requires("TheColor").HasValue(Yellow || White)

Bad example, but hopefully you get the picture!

No, It is Immpossible.

The Entity framework allows you to display only the intersection of conditions, not the union of conditions.
You can see this both in design [1] and in EDMX syntax [2].
* First, the code should have the same display capabilities.

[2] edmx "Open With..." → "Automatic Editor Selector (XML)" , ( intellisense), "" .
