Subject:	ARIA processing in host langauges

In section 7. Implementation in Host Languages of WAI-ARIA 1.0
It states that

"User Agent processing for roles is defined in the WAI-ARIA User Agent
Implementation Guide [ARIA-IMPLEMENTATION]." [1]

"When these attributes appear in a document instance, the attributes will
be processed as defined in this specification." [1]

Why are the processing rules defined in the UA gudie for role, but not for
aria-* ?
