Reference

Facts to look up. The specification is the full and exact reference; these pages give its parts at a glance.

• Elements and attributes: every element, what it may hold and where it may be, and its attributes, from the checker's own table and the specification's words.
• The scene API: the holoml object, things, and events, each member with its declaration in Web IDL.
• Codes: the syntax errors and the problems a checker reports, with their meanings and the conformance samples that show them.
• HyperSpace 3D's limits: what one page may use in HyperSpace 3D, the first renderer.
• The grammar, as files: the syntax in ABNF, the structure in RELAX NG, and the scene API in Web IDL.

The elements, scene API, and codes pages are made from the checker's table, the Web IDL, the conformance samples, and the specification by pnpm reference:update, and a test checks that they are up to date.
