The element ui:default

The element can be used at the beginning of ui:page and ui:template to define default values for template parameters that are not passed to the template.

Declaration

Level: Control structure

<!ELEMENT ui:default ANY>

<!ATTLIST ui:default
          name     NMTOKEN    #REQUIRED
>
Attributes

  • name: The name of the parameter

Sub elements

All page body elements may occur in ui:default.

Known Bug

Template parameters inside ui:default are currently not expanded. This is likely to change in the future.

Example that does not work yet:

<ui:template name="foo" from-caller="a b">
  <ui:default name="a">44</ui:default>
  <ui:default name="b">$a + $a = 88</ui:default>
  ...
</ui:template>
