Add expressions

edm:Eq

edm:Ne

edm:Ge

edm:Gt

edm:Le

edm:Lt

edm:And

edm:Or

edm:Not

edm:Not requires one child element of Boolean type
edm:And and edm:Or require two child elements of Boolean type
The other expressions require two child elements of comparable type.

Allow edm:If to have only two child elements if and only if it is a direct child of edm:Collection. This is needed to conditionally add elements to a collection, and using edm:Null as the third child does not convey this meaning.

Description

<edm:If> takes a boolean expression as its first argument, but the choice here is pretty limited. For example I'm unable to compare the values of two strings, or the result of two path expressions, or test the result of an expression for "null"
