Text or text list. In the case of a single body field being specified, a single string is returned which is the first 100 characters or first two paragraphs (whichever is less) of the field with newlines and tabs converted to spaces. A paragraph is defined by a terminating newline character. For rich text fields all formatting is removed. If the field has less than 100 characters, the entire field is returned. If a list of field names is supplied, then a text list is returned, with each list element containing the abstracted version of the corresponding field in the field list.
If a field is of an invalid type, or can't be found, the string returned is the name of the field that was passed into @AbstractSimple.
Nota If the behavior of @Abstract is desired, where the result is a single, space-separated, string of abstracted results, apply @Implode to the result of @AbstractSimple
