A method to request a DOM implementation.
Params:
  • features – A string that specifies which features are required. This is a space separated list in which each feature is specified by its name optionally followed by a space and a version number. This is something like: "XML 1.0 Traversal Events 2.0"
Returns:An implementation that has the desired features, or null if this source has none.
