Required Element Summary

Required Elements
Modifier and Type Required Element Description

String name
The defined name of this datatype

Optional Element Summary

Optional Elements
Modifier and Type	Optional Element	Description
`boolean`	`isSpecialization`	Set this to true (default is false) for any types that are really only a specialization of another type.
`Class<? extends IBaseDatatype>`	`profileOf`	Indicates that this datatype is a profile of the given datatype, which implies certain parsing/encoding rules (e.g.

- Element Detail
  - name
```
String name
```
    The defined name of this datatype
- - isSpecialization
```
boolean isSpecialization
```
    Set this to true (default is false) for any types that are really only a specialization of another type. For example, BoundCodeDt is really just a specific type of CodeDt and not a separate datatype, so it should have this set to true.
    
    Default:
    
    false
- - profileOf
```
Class<? extends IBaseDatatype> profileOf
```
    Indicates that this datatype is a profile of the given datatype, which implies certain parsing/encoding rules (e.g. a choice element named foo[x] which allows a Markdown value will still be encoded as fooString because Markdown is a profile of string.
    
    Default:
