Detailed Description

An input registration is a specification of how an input value will be provided to a computation callback at evaluation time.

An input registration is a sequence of:

• zero or more object accessors, which provide access to one or more scene objects that act as computation providers, and which must be followed by:
• exactly one value specifier, which request a value from the computation provider(s), and which may be followed by:
• zero or more input options, which modify the behavior of the resulting input registration.

For convenience, certain object accessor/value specifier/input option sequences may be replaced by an alias, which compactly represents a compound input registration.
