Provide support for subsitution strings

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a select that contains substitutions

For example:
<select id="mySubstitution" resultClass="java.util.HashMap">
        select * from $table$
    </select>


What is the expected output? What do you see instead?
$table$ is highlighted as an error
It'd be great if $table$ was understood and you could provide a value when 
support for running SQL statements comes along.



Please provide any additional information below.
