DI token for parent CngxTagGroup <-> child CngxTag ARIA wiring
CNGX_TAG_GROUP
Tokenv0.1.0WCAG AA
InjectionToken<CngxTagGroupHost>
Description#
DI token for parent CngxTagGroup <-> child CngxTag ARIA wiring.
Atomic-decompose rule 4 - communication via InjectionToken,
never via concrete parent class injection.
CngxTag injects the token { optional: true } and, when present,
derives its own role="listitem" from host.semanticList() via a
single computed(). When absent (Tag rendered outside any group),
the role attribute stays unset.
Defaults to no provider - the token resolves to null for any
CngxTag that lives outside a CngxTagGroup.
