The function showSummary defined in the domain 'Domain': 

    showSummary: % -> Void
      ++ showSummary(d) prints out implementation detail information
      ++ of domain `d'.

returns the error message: 

   >> System error:
   |getConstructorPredicateFromDB| is invalid as a function.


axiom
showSummary(Integer)
--------------------Predicate summary-------------------
   >> System error:
   |getConstructorPredicateFromDB| is invalid as a function.

showSumary works
at the moment -- only for non-builtin constructors.

RomanNumeral? is not built-in --Bill Page, Wed, 28 May 2008 18:35:48 -0700 reply
Right?

axiom

Type: RomanNumeral?

axiom
showSummary(RomanNumeral)$Domain

   |getConstructorPredicateFromDB| is invalid as a function.

a typo in the name of the Lisp function. Now fixed.

Here is what I meant by the comment on `builtin' domain: 

  (2) -> showSummary Union(Integer,String)
  --------------------Predicate summary-------------------
  --------------------Attribute summary-------------------

   Union is an unknown constructor and so is unavailable. Did you mean
      to use -> but type something different instead?

this is clearly not right. But the reason it is that way is that Union is a builtin constructor.

Now showSummary works for non-builtin domains (when it doesn't it surely is a bug :-)
