Remarks
The method looks for the most specific extension by the given parameters.
During lookup, the method prefers more specific attribute values to less specific (first, extension marked with value equal to _attribute, then extension marked with value equal to _attribute.getMoreGeneral(), and so on).
If several extensions are bound to the same attribute value, extensions that support the SysIConditionalExtension interface are better.
