Doctype-class {XML} | R Documentation

## Class to describe a reference to an XML DTD

### Description

This class is intended to identify a DTD by SYSTEM file and/or PUBLIC catalog identifier. This is used in the DOCTYPE element of an XML document.

### Objects from the Class

### Slots

`name`:
  Object of class `"character"`. This is the name of the top-level element in the XML document.
`system`:
  Object of class `"character"`. This is the name of the file on the system where the DTD document can be found. Can this be a URI?
