The UML DTD
When you import or export Enterprise Architect packages to XMI, the import or export process can be validated using a Data Type Definition (DTD).

Notes on DTDs |
The XML parser uses the DTD to validate the correctness of the model and to check that no syntactical errors have occurred. It is always best to use a DTD when moving packages between Enterprise Architect models as it ensures correctness of the XMI output, and prevents attempted imports of incorrect XML. Several DTDs for XMI/UML exist; the OMG defines a standard UML1.3 DTD for use in XMI 1.1, and Enterprise Architect uses an extension of this with some additional element extensions for non-standard UML types, such as testing details. Whenever you read an XML file, the XML parser looks in the current directory for the DTD - if specified - using the DOCTYPE element in the XML file. If the parser cannot find the DTD, it records an error and aborts processing; you must ensure the UML_EA.DTD file is in the current XML output path (generated by default).
