This is a Stencila-native type corresponding closely to the JATS <supplementary-material> element.

It is used to attach supplementary works to a document while still allowing them to appear as block content near the material they support, such as within a figure caption or a dedicated supplementary materials section. This lets Stencila model supplements as document content rather than only as distant metadata attachments.

Key properties include workType, label, caption, and target.
