fill-slot: Customize a macro

  Syntax

    'metal:fill-slot' syntax::
   
      argument ::= Name

  Description

    The 'metal:fill-slot' statement customizes a macro by replacing a
    *slot* in the macro with the statement element (and its content).

    The 'metal:fill-slot' statement must be used inside a
    'metal:use-macro' statement.

    Slot names must be unique within a macro.

    If the named slot does not exist within the macro, the slot
    contents will be silently dropped.

  Examples

   Given this macro::

      <p metal:define-macro="hello">
        Hello <b metal:define-slot="name">World</b>
      </p>
 
    You can fill the 'name' slot like so::

      <p metal:use-macro="container/master.html/macros/hello">
        Hello <b metal:fill-slot="name">Kevin Bacon</b>
      </p>
