MoDisco/Components/XML

The Generic XML Metamodel represents a subset of concepts defined in W3C XML Recommendation.

Its purpose is to represent XML content without taking care of conformance to concepts described in a Document Type Definition(DTD) or in a XML Schema Description (XSD) (i.e. without having a metamodel dedicated to one or many DTD/XSD).

It is an alternative to the metamodel definition provided with EMF plugins (nsuri : http://www.eclipse.org/emf/2003/XMLType) : we think that a more understandable model navigation, without the use of the Extended Ecore Modeling FeatureMap type, can be proposed to the end user. In return, some filtering (on node children) might be more time expensive.

Ecore Generic XML metamodel definition

W3C XML Recommendation describes those concepts in document and logical structures sections. Concepts for Document Types Declarations are not managed here.
