Attach reusable preambles and postambles to a template.

Overview

Attach reusable preambles and postambles to a template. Composite templates improve reuse but add a publish-time compilation step. Treat component and assignment changes as release events.

Key points

• Assignments identify template, component, placement, order, and enabled state.
• The component must be active and visible to the instance.
• Placement must match the component type.
• Replacing assignments invalidates the compiled package.
• Assignment conditions are stored but not currently supported by compilation.

Recommended procedure

1. Confirm the base package and body are compatible.
2. Select active preamble and postamble components.
3. Set deterministic placement order.
4. Scan, validate, compile, and render a regression sample.

Troubleshooting

Compilation reports a declaration conflict

Rename or centralize variables, parameters, or named templates that share a name but differ in content.

The component order is rejected

Use unique sort-order values within PREAMBLE and POSTAMBLE.

Rendering returns TEMPLATE_COMPILATION_REQUIRED

The compiled package is absent or stale; validate and compile before rendering.
