Reference Overview

The reference section is the fast path for lookup. It complements the user guides by cataloging supported syntax and implementation-backed behavior.

Reference map

• IDL Elements: declarations, types, and behavior
• Annotations: transport, optionality, and target-specific annotations
• Pragmas: compiler directives recognized by xidlc
• Targets: built-in generators, aliases, outputs, and common runtime pairings

How to use this section

• Start here when you need syntax, not a tutorial
• Follow links to user guides for worked examples
• Follow links to RFCs for normative transport rules
• Follow links to source files when you need implementation detail
