Usually, you want the disable attribute to not show up at when the tag
is /not/ disabled. You can do this by not putting the attribute in
your markup (<input type="text" wicket:id="foo" value="bar" />),
provide the second AttributeModifier argument 'true' (so attributes
will be added when they do not exist yet), and - important - let your
replacement model return null when the component is not enabled. If
the replacement model returns null, the attribute modifier will do
nothing, which is what you want in this case.
