The proposal is to modify the following filters:
- comparison filters: equals, not equals, gt, gte, lt, lte, between, like
- all geometry filters
to allow collections of values as input, besides single values. if an
expression returns a collection of values rather than just a single
value, the filters will be able to handle it. The way these collection
of values is interpreted by the filter should be according to the X-path
standard, i.e. the result will be the OR-ed aggregation of all possible
combinations. For example, if we compare the following values
(x, y, z) = (a, b)
the result will be true if x=a OR x=b OR y=a OR y=b OR z=a OR z=b.
