XML representation of SQL queries?

[Richard Tobin <richard@inf.ed.ac.uk>]

Is there a standard way of representing SQL queries in XML?
I'm imagining something like:

  <select>
    <column>name</column>
    <column>age</column>
    <from>employees</from>
    <where>
       ...
    </where>
  </select>
