xlink:actuate

A linking element's xlink:actuate attribute has four predefined values:

onRequest
onLoad
other
none

<IMAGE xmlns:xlink="http://www.w3.org/1999/xlink" 
  xlink:type="simple" xlink:href="logo.gif"
  xlink:actuate="onLoad"/>
  xlink:show="embed"

Like all attributes in valid documents, the actuate attribute must be declared in the DTD in a <!ATTLIST> declaration for the link elements in which it appears. For example:

<!ELEMENT IMAGE EMPTY>
<!ATTLIST IMAGE 
 xmlns:xlink CDATA #FIXED "http://www.w3.org/1999/xlink"
  xlink:type CDATA #FIXED "simple"
  xlink:href CDATA #REQUIRED
  xlink:show    (new | replace | embed) "embed"
  xlink:actuate (onRequest | onLoad)    "onLoad"
>
