Element Attributes Content Parent
<ncl> id, title, xmlns (<head>?, <body>?)


Name Value Description
id It may receive any string value that begins with a letter or an underscore and that only contains letters, digits, “.”, and “_”. The id attribute uniquely identifies the element within a document.
title String. The title attribute contains advisory information. Values of the title attribute may be rendered by user agents in a variety of ways.
xmlns” or “ The xmlns attribute declares an XML namespace—in other words, it declares the primary collection of XML-defined constructs the document uses. The attribute's value is the URL identifying where the namespace is officially defined. Two values are allowed for the xmlns attribute: “” and “”, for the Enhanced and Basic DTV profiles, respectively. An NCL player shall know that the schemaLocation for these namespaces is, respectively: “” and “”.
