## NAME
    [XML::DOM::DOMImplementation](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM%3A%3ADOMImplementation/markdown) - Information about [XML::DOM](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM/markdown) implementation

## DESCRIPTION
    The DOMImplementation interface provides a number of methods for performing operations that are
    independent of any particular instance of the document object model.

    The DOM Level 1 does not specify a way of creating a document instance, and hence document
    creation is an operation specific to an implementation. Future Levels of the DOM specification
    are expected to provide methods for creating documents directly.

  METHODS
    hasFeature (feature, version)
        Returns 1 if and only if feature equals "XML" and version equals "1.0".
