The target attribute is a prohibited attribute of the a element, in the strict DTD.
A document type definition (DTD) is a collection of markup declarations that establishes a document type for a markup language belonging to the SGML family (GML, SGML, XML, HTML). The acceptable building pieces of an XML document are specified by a DTD. A list of components and characteristics that have been verified specifies the document structure. A DTD can be referenced externally or inline within an XML document. In an XML or SGML document, a document type declaration links a DTD to it (DOCTYPE). Near the beginning of an XML document, the syntactic fragment doctypedecl contains the DOCTYPE. The declaration proves that the file is a specimen of the type specified by the cited DTD.
