• As with all other attributes, the xlink:title and xlink:role attributes should be declared in the DTD for all the elements to which they belong. For example, this is a reasonable declaration for the above AUTHOR element:

  <!ELEMENT AUTHOR (#PCDATA)>
  <!ATTLIST AUTHOR
    xmlns:xlink CDATA #FIXED "http://www.w3.org/1999/xlink"
    xlink:type  CDATA #FIXED "simple"
    xlink:href  CDATA #REQUIRED
    xlink:title CDATA #IMPLIED
    xlink:role  CDATA #IMPLIED
