Capabilities matrix

A single-page map of every IDML construct and how far the Paged renderer takes it — parsed, rendered, or not yet. Generated live from the capability registry; the same status as the support badge on each feature's own page.

In short Every IDML construct this reference documents, with how far the Paged renderer takes it — the same support badge you see beside each feature in its chapter, gathered in one place. This page is generated from the capability registry: it cannot drift from the engine, because it is the engine's recorded status. For the full cross-platform view (editor, server, plugins), see the platform capability matrix.

How to read this

Each cell's glyph carries the meaning, so the grid reads in greyscale:

Supported · verified — shipped, and a test verifies it.
A partial cell means the construct is read but only partly acted on; a planned cell means it isn't handled yet. The note on each row's chapter page explains the specifics.

The columns are the engine layers each construct touches — most IDML constructs live in Parser and Renderer, with Mutation where editing applies.
