# Interface DOMImplementation

The **`DOMImplementation`** interface represents an object providing methods which are not dependent on any particular document. Such an object is returned by the Document.implementation property.

    [createDocument](#createdocument-1)(  
        namespace: string | null,  
        qualifiedName: string | null,  
        doctype?: [DocumentType](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.DocumentType/) | null,  
    ): [XMLDocument](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.XMLDocument/);  
    [createDocumentType](#createdocumenttype-1)(  
        name: string,  
        publicId: string,  
        systemId: string,  
    ): [DocumentType](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.DocumentType/);
