  2. The XML Declaration The first line of any XML document contains the XML declaration: <?xml version=“1.0”?> If the file has an associated XSL stylesheet, it is declared next: <?xml-stylesheet href=“filename” type=“text/xsl”?> where “filename” is the URL of the associated stylesheet.

  3. Doctype Declaration The doctype declaration follows the XML declarations: <!DOCTYPE Root_element_name SYSTEM "Filename.dtd"> where “Filename.dtd” is the URL of the external dtd. Additions or references to the base dtd can be added between brackets “[ ]”: <!DOCTYPE Root_element_name SYSTEM "Filename.dtd”[ <!ENTITY %external.xml'INCLUDE'> <!ENTITYinternal“Ruffles”> <!ENTITY %charactersetSYSTEM ‘URL’> % characterset; ]>

  4. Doctype Declaration A dtd can also be included in the body of the document rather than in an external document: <!DOCTYPE Root_element_name SYSTEM [ Element, Attribute and, Entity Declarations... ]> where all the element, attribute, and entity declarations occur between the square brackets [ ].

  5. DTD Operators When declaring elements and attributes, use the following symbols to indicate relationships: ? Optional, 0 or 1 + Required, 1 or more * Optional and repeatable, 0 or more | Or , Sequential

  6. Element Declaration Element declarations take the following form: <!ELEMENTTagname (Content Model)> The Content Model may contain: * Specific tagnames or ANY (essentially any and all tagnames) * #PCDATA (essentially simple characters) * EMPTY (indicating an empty tag)

  7. Sample Element Declarations Simple text: <!ELEMENT formula (#PCDATA)> Mixed content: <!ELEMENT dateline (#PCDATA | date | time | name | address | anchor | gap | figure | index | interp | interpGrp | lb | milestone | pb)* > Complex: <!ELEMENT creatorInfo (creator,(creatorAddress|xref)*,(notes)?, (responsibleFor)*)> Empty: <!ELEMENT pb EMPTY >

  8. Attribute Declaration • Attribute declarations take the following form: • <!ATTLISTElement-name Attribute_name Type Default-value> • Attribute types can have the following values: • CDATA: Characters data that is not markup; • Enumerated: A list of values from which only one may be chosen; • ID: A unique name not shared by any other ID type in the document; • IDREF: The value of an ID type attribute of an element in the document; • IDREFS: Multiple IDS of elements separated by whitespace; • ENTITY: The name of an entity declared in the DTD; • ENTITIES: Names of multiple entitities declared in the DTD, separated by whitespace.

  9. Attribute Declaration • Attribute declarations take the following form: • <!ATTLISTElement-name Attribute_name Type Default-value> • Default types can have the following values: • #REQUIRED: The attribute must be included and given a value; • #IMPLIED: The attribute is optional • #FIXED: The attribute is required and the value is declared in the attribute declaration within quotes immediately after the default value declaration.

  10. Sample Attribute Declaration <!ATTLIST p corresp IDREFS #IMPLIED next IDREF #IMPLIED prev IDREF #IMPLIED ana IDREFS #IMPLIED id ID #IMPLIED n CDATA #IMPLIED lang IDREF #IMPLIED rend CDATA #IMPLIED TEIform CDATA "p" >

  13. Entity Declarations Document-level entity declarations take the following form: <!ENTITY Name "Replacement text"> Within a DTD, references to external parameter entities take the following form: <!ENTITY % Name "Replacement text URL"> % Name;
