The class name identifies the class and follows Defclass:.

Class names:

• can contain any alphabetic character, numeric character, the "_" and "?," as well as the special character "%."

• are not case sensitive.

• must begin with an alphabetic character or a percent sign "%". Class names that begin with a "%" or end with "mixin" are considered hidden and do not appear in the Knowledge Fusion Navigator list of classes.

• must not start with two percent signs "%%", because that is reserved for system attributes.

• cannot be a Knowledge Fusion reserved word.

• the name should not exceed 100 characters.

• that begin with a numeric character (example: 1234_test) generate a Knowledge Fusion parse error.
