Overview

Lightweight attribute wrapper. libtaurus v0.4.4 doesn't expose per-attribute pointers (no TaurusAttribute accessors in the public API), so an Attr is a (name, value, parent_element) triple. Mutation goes through the parent element via #[]. Once upstream adds attribute-level accessors, this can become a pointer-backed wrapper.
