// The test verifies that removed attributes which are later on kept due to descriptors correctly warn.
// The setup is:
// - test assembly with the AttributeToRemoveAttribute type
// - link attributes.xml which marks the attribute for removal (applied early, in this case via command line, but could be a embedded in the test assembly)
// - the attribute is used by the test assembly
// - another assembly lib.dll is added and is referenced (after the attribute is used/marked)
// - This new assembly has a descriptor which marks the entire test assembly (note that it marks the TEST assembly)
// - This marking causes the warning, as it's an explicit request to keep the attribute which was supposed to be removed
