Parasitol Int 50, 93–104 (2001).37.Ronaghi, M. Pyrosequencing sheds light on DNA sequencing. When a start or end tag token is created, its self-closing flag must be unset (its other state is that it be set), and its attributes list must be empty. However, if the user agent delays too long to obtain data to determine the encoding, then the cost of the delay could outweigh any performance improvements from the preparse. This encoding is rarely used for publicly-facing Web content. For the purposes of conformance checkers, if a resource is determined to be in the HTML syntax, then it is an HTML document. As stated in the terminology section, references to element types that do not explicitly specify a namespace always refer to elements in the HTML namespace.
