---% ADDINFORMATION CODE
---% This code adds various items to the special value of $Information,
---% in order to keep track of all the compiler's information about
---% various categories and similar objects
---% An actual piece of (unconditional) information can have one of 3 forms:
---% (ATTRIBUTE domainname attribute)
---% --These are only stored here
---% (SIGNATURE domainname operator signature)
---% --These are also stored as 'modemap' properties
---% (has domainname categoryexpression)
---% --These are also stored as 'value' properties
---% Conditional attributes are of the form
---% (%when
---% (condition info info ...)
---% ... )
---% where the condition looks like a 'has' clause, or the 'and' of several
---% 'has' clauses:
---% (has name categoryexpression)
---% (has name (ATTRIBUTE attribute))
---% (has name (SIGNATURE operator signature))
---% The use of two representations is admitted to be clumsy
