Remarks

ElementFilter is either an ElementParameterFilter or an ElementLogicalFilter representing a Boolean combination of ElementParameterFilters. In addition, we check that each ElementParameterFilter satisfies the following conditions: Its array of FilterRules is not empty and contains:

Any number of FilterRules of type FilterValueRule, FilterInverseRule, and SharedParameterApplicableRule or
Exactly one FilterCategoryRule containing only one category from categories stored by this ParameterFilterElement or
Exactly two rules: the first one is a FilterCategoryRule containing only one category from categories stored by this ParameterFilterElement and the second one is a FilterRule of type FilterValueRule, FilterInverseRule, or SharedParameterApplicableRule.

Note that cases in the second and third bullet are currently allowed only if the parent node of ElementParameterFilter is LogicalOrFilter.
