Cargo Features

ProvenanceMark has no features set by default.

provenance-mark = { version = "0.3.2", features = ["envelope"] }
envelope = bc-envelope

Affects mark::register_tags_in, mark::register_tags

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
