@viirya thanks for the thorough trace. Addressed the qualifier/metadata finding in 4bc6601 exactly as you and @cloud-fan suggested: the lifted alias now keeps `a`'s child/exprId but adopts `attr`'s name, qualifier, and metadata (following the `RemoveRedundantAliases` precedent you pointed to). The name-preservation test is extended to cover a top attribute with a different qualifier and metadata as well. -- This is an automated message from the Apache Git Service.
