    - #### setOutput

          public void setOutput​(java.io.File output)

      The output file.
      Parameters:
        `output` - the output file

    - #### add

          public void add​(AntStructure.StructurePrinter p)

      The StructurePrinter to use.
      Parameters:
        `p` - the printer to use.

    - #### execute

          public void execute()
                       throws BuildException

      Build the antstructure DTD.
      Overrides:
        `execute` in class `Task`
      Throws:
        `BuildException` - if the DTD cannot be written.

    - #### isNmtoken

          protected boolean isNmtoken​(java.lang.String s)

      Does this String match the XML-NMTOKEN production?
      Parameters:
        `s` - the string to test
      Returns:
        true if the string matches the XML-NMTOKEN

    - #### areNmtokens

          protected boolean areNmtokens​(java.lang.String[] s)

      Do the Strings all match the XML-NMTOKEN production?

      Otherwise they are not suitable as an enumerated attribute, for example.

      Parameters:
