Action: Tag is replaced by the value of a variable or expression.
Options:
- arg: get value from http request named name instead of using stored variable
  - Retrieves value from $wgRequest->getVal(name, default);
- codes: process with ShowHTML() before output
- default= default value to use if argument named arg is not set
  - This may eventually be used to fill in a value in other cases, but for now it doesn't.
- index= offset into array named name
- isolate: use extreme isolation to prevent parsing before output
- lcase: convert to lowercase before output
- len= maximum number of characters to include; truncate after nth character
- name= name of variable to retrieve
- raw: output should not be parsed (usage is restricted)
- ucase: convert to uppercase before output
- val= expression to use instead of variable name
