There are a number of predefined templates that can be used by application programmers.

• wd-null: This template expands to the empty string.

• wd-int: This template expands to the value of the parameter $int. It is intended to be used in iterators like ui:iterate:

  <ui:iterate template="wd-int" variable="x">
    <ui:iter-separator>, </ui:iter-separator>
  </ui:iterate>
  

  This example iterates over the contents of x (either a dynamic enumerator or an associative variable), and prints the internal values, separated by commas.

• wd-ext: This template expands to the value of the parameter $ext. It is intended to be used in iterators like ui:iterate:

  <ui:iterate template="wd-ext" variable="x">
    <ui:iter-separator>, </ui:iter-separator>
  </ui:iterate>
  

  This example iterates over the contents of x (either a dynamic enumerator or an associative variable), and prints the external values, separated by commas.
