Here is my counter proposal:

public interface ModularParser extends Parser {
    boolean hasModule(String moduleName);
        // returns true if the named module is supported, false otherwise.
        // return value does not indicate whether the module is enabled or
        // module version should be encoded in the module name

    boolean getModuleState(String moduleName);
        // returns true if the named module is enabled, false otherwise.

    boolean setModuleState(String moduleName, boolean enable);
        // enables or disables a named module.
        // Result reflects the resulting state of the module.

    ModuleHandler getModuleHandler(String moduleName);
        // returns named module's handler or null if there is no previously
        // handler or if the module is not supported.

    boolean setModuleHandler(String moduleName, ModuleHandler handler);
        // sets named module's handler.
        // returns true if successful or false if failed to set the handler
due to
        // lack of support or other reasons.

    // following two might be more controversial but they are definitely

    Object getModuleProperty(String moduleName, String propName);
    boolean setModuleProperty(String moduleName, String propName, Object

public interface ModuleHandler {
    // still empty

Differences are:

1. Does not use exception
2. Combined features with handler (liason?) types
3. Names changed for clarity and coherency

This is a 'grab bag' proposal so please take any idea you find useful and
throw away the rest.
