Operation XML descriptors

This area covers the XML descriptors of technological operations — how to describe and register an operation, and how the shipped operations are organized. It is not a full manual of what each operation does; it is about authoring and understanding their XML descriptors. It builds on the XMLProperties framework (read the descriptor syntax and expression language first).

• Operation XML descriptors — the anatomy of an operation descriptor: the registration record, choosing a base type, the header, parameters, ContainerID / SolverID, MultiGroup, and where your file goes.
• Operation hierarchy reference — the full inheritance tree of every shipped operation (ID, caption, parent, container/solver, source file), to help you pick a base type. Generated — do not hand‑edit.

See the XMLProperties framework for the shared ground rules (don't edit Supplement, where the shipped files live, example conventions), and the documentation root for the intended audience.
