Is there a way to programmatically get list of valid values/datatypes for Simulink block parameter?

Simulink Block Specific parameters documentation lists the values and/or datatype each parameter of the block accept. Is there an api or function that allows us to get this information programmatically?

For example, Delay dialog box parameters 'ShowEnablePort' which can only be set to 'on' or 'off'.

I'm not sure that this can be done in general. But for dialog parameters that areof type 'enum', the options can be obtained by:

>> d=get_param(gcb,'DialogParameters')

d = 

  struct with fields:

                        DelayLengthSource: [1×1 struct]
                              DelayLength: [1×1 struct]
                    DelayLengthUpperLimit: [1×1 struct]
                   InitialConditionSource: [1×1 struct]
                         InitialCondition: [1×1 struct]
                            ExternalReset: [1×1 struct]
                           ShowEnablePort: [1×1 struct]
                 PreventDirectFeedthrough: [1×1 struct]
                 DiagnosticForDelayLength: [1×1 struct]
    RemoveDelayLengthCheckInGeneratedCode: [1×1 struct]
                          InputProcessing: [1×1 struct]
                        UseCircularBuffer: [1×1 struct]
                               SampleTime: [1×1 struct]
                                StateName: [1×1 struct]
           StateMustResolveToSignalObject: [1×1 struct]
                        StateSignalObject: [1×1 struct]
                        StateStorageClass: [1×1 struct]
         CodeGenStateStorageTypeQualifier: [1×1 struct]

>> d.DelayLengthSource

ans = 

  struct with fields:

        Prompt: 'Delay length source:'
          Type: 'enum'
          Enum: {'Dialog'  'Input port'}
    Attributes: {'read-write'  'read-only-if-compiled'  'dont-eval'  'link-instance'}

>> d.DelayLengthSource.Enum

ans =

  1×2 cell array

    {'Dialog'}    {'Input port'}

For parameters of type 'boolean', I'll just conjecture that the choices are either 'on' or 'off'.

For parameters of type 'string' I don't know what to say:

>> d.DelayLength

ans = 

  struct with fields:

        Prompt: 'Delay length:'
          Type: 'string'
          Enum: {}
    Attributes: {'read-write'  'read-only-if-compiled'  'link-instance'}

I don't know and couldn't find in doc if there are any other types of dialog parameters.
