call: Call a method

  The 'call' tag lets you call a method without inserting the results
  into the DTML output.

  Syntax

    'call' tag syntax::

      <dtml-call Variable|expr="Expression">

    If the call tag uses a variable, the methods arguments are passed
    automatically by DTML just as with the 'var' tag. If the method is
    specified in a expression, then you must pass the arguments yourself.

  Examples

    Calling by variable name::

      <dtml-call UpdateInfo>

    This calls the 'UpdateInfo' object automatically passing arguments.

    Calling by expression::

      <dtml-call expr="RESPONSE.setHeader('content-type', 'text/plain')">
