# PureXML validation coverage registry (validation-rules.md).
# Each public type is either a SUBJECT (validated by named rule sets) or EXCLUDE
# (with reason). Namespace prefixes EXCLUDE_NS auto-exclude infrastructure types.
# WATCH_NS requires every newly discovered type in that namespace be listed here.
