DS/ISO/IEC 19757-9:2009 Information technology - Document Schema Definition Languages (DSDL) - Part 9: Namespace and datatype declaration in Document Type Definitions (DTDs)
This part of ISO/IEC 19757 defines a language that is designed to extend the declarative functionality of an XML DTD to include— declaring one or more namespaces to which some or all of the element and attribute names in a DTD belong,— declaring constraints on the content of elements with content model ANY to contain elements whose names belong to one or more specified namespaces,— declaring datatypes for elements that contain data content only and for attribute values.Two alternative syntax bindings for this language are defined. The first syntax binding uses XML processing instructions and is designed to enable declarations in this language to be embedded
