The sdp: namespace holds presentation rendering directives — declarative effects applied when a document renders as a slide deck. It covers slide-level effects (sdp:transition, sdp:background with its sdp:bgFrom/`sdp:bgVia`/`sdp:bgTo` colour parameters, sdp:autoAnimate), block-level effects (sdp:fragmentItems, sdp:highlight), image filters (sdp:blur, sdp:grayscale, sdp:sepia, …), and the slide-furniture classes sdp:SpeakerNotes, sdp:Caption, sdp:Header, and sdp:Footer.Copy as claim

Membership in this namespace is derived by the Lexicon from the declaration above — see Namespace Definition.Copy as claim
