A method and system for providing help information for a computer program. The help system provides help information based on a schema that specifies the structure of a valid computer program. The schema provides definitions of program element types that are specific instances of a program element type derived from more general program element types. The help system identifies a "derivation" of program element types relating to the selected program element. The help system then displays the derivation to the user. The user can then select to display documentation associated with the displayed program element types.
