[...] So in summary it's ugly, has a high cognitive load, doesn't express the developers intent (actually even expresses the opposite), is hard to spot when reading code, and is error prone. Hope this helps. :) It does, thank you. At the risk of asking the obvious question, why not use the extends= syntax you mentioned? <my-button extends="button" attributes>Push</my-button> It follows the expected X extends Y convention, and makes it reasonably clear what the attributes have been applied to I think.
