Validating dtd Suriname ive camgirls
Note that this DOCTYPE can only appear after the optional XML declaration, and before the document body, if the document syntax conforms to XML.
This includes XHTML documents: Finally, the document type definition may include no subset at all; in that case, it just specifies that the document has a single top-level element (this is an implicit requirement for all valid XML and HTML documents, but not for document fragments or for all SGML documents, whose top-level elements may be different from the implied root element), and it indicates the type name of the root element: DTDs describe the structure of a class of documents via element and attribute-list declarations.
DTD markup declarations declare which element types, attribute lists, entities, and notations are allowed in the structure of the corresponding class of XML documents.
An element type declaration defines an element and its possible content.
However, notation names usually follow a naming convention that is specific to the application generating or using the notation: notations are interpreted as additional meta-data whose effective content is an external entity and either a PUBLIC FPI, registered in the catalogs used by XML or SGML parsers, or a SYSTEM URI, whose interpretation is application dependent (here a MIME type, interpreted as a relative URI, but it could be an absolute URI to a specific renderer, or a URN indicating an OS-specific object identifier such as a UUID).
Note that any valid SGML or XML document that references an external subset in its DTD, or whose body contains references to parsed external entities declared in its DTD (including those declared within its internal subset), may only be partially parsed but cannot be fully validated by validating SGML or XML parsers in their standalone mode (this means that these validating parsers don't attempt to retrieve these external entities, and their replacement text is not accessible).
Element declarations name the allowable set of elements within the document, and specify whether and how declared elements and runs of character data may be contained within each element.
Attribute-list declarations name the allowable set of attributes for each declared element, including the type of each attribute value, if not an explicit set of valid values.
A DTD defines the valid building blocks of an XML document.
It defines the document structure with a list of validated elements and attributes.
