The 'show' attribute is used to communicate the desired presentation

of the ending resource on traversal from the starting resource; it's
|
|
24
|
value should be treated as follows:
|
|
25
|
new - load ending resource in a new window, frame, pane, or other
|
|
26
|
presentation context
|
|
27
|
replace - load the resource in the same window, frame, pane, or
|
|
28
|
other presentation context
|
|

|
embed - load ending resource in place of the presentation of the

starting resource
|

The 'actuate' attribute is used to communicate the desired timing
|

50
|
of traversal from the starting resource to the ending resource;
|
|
51
|
it's value should be treated as follows:
|
|
52

onLoad - traverse to the ending resource immediately on loading
|
|
53
|
the starting resource
|
|
54
|
onRequest - traverse from the starting resource to the ending
|
|
55
|
resource only on a post-loading event triggered for
|
|
56
|
this purpose
|
|
57

other - behavior is unconstrained; examine other markup in link

none - behavior is unconstrained
