5.3.9 <al-lookup>

The <al-lookup> tag uses a dictionary-style lookup to choose one of the contained <al-item> HTML fragments. If no <al-item> tag matches, then the tag returns any content that was not enclosed by an <al-item> tag. The <al-item> key values are derived by evaluating their expr attribute.

The <al-lookup> element will either be expanded in place if an expr attribute is given or, if named with an name="..." attribute, expanded later via an <al-value> lookup="..." tag.
