Referenceintroduction

<introduction>

A block container for the introduction of a section

<introduction> is a block container for the introductory content of a section. It groups content without adding a heading, numbering, or any other visible chrome. Its primary use is inside a sectional component whose asList attribute is true — most commonly <problems> or <exercises> — because in that case ordinary prose children are silently dropped, and an <introduction> is one of the few non-sectional children that still renders.

Examples

Example: <introduction> at the start of a <problems> list

The <introduction> renders before the numbered list of <problem>s. The same pattern works inside <exercises> and any other sectional component with asList="true".

Example: prose that needs to be wrapped

The bare-string instructions above are dropped because <problems> has asList="true" by default. Wrap them in an <introduction> to make them visible:

Example: <introduction> as a named, referenceable container

Like any block container, an <introduction> can be named and referenced elsewhere in the document.
