1//! Supported ifcXML release profiles.

3/// A release-specific ifcXML namespace/profile contract.
4///
5/// A profile fixes the namespace and schema token, not the layout: native
6/// output under a profile is not valid against the release XSD. The XSD's
7/// own configuration is a separate layout ([`crate::XmlLayout::Xsd`]),
8/// which this crate reads and writes.
