Associate a file extension with an application

[Joe Riel]

How can Thunar be configured to associate a file extension with a
particular application?

In my case, I'd like to double-click on a Maple worksheet (extension
.mw) and have it be opened with the Maple application.  However, a .mw
file uses xml formatting, so if I click File -> Properties in Thunar
and then try to change the application to Maple, it wants to associate
*all* xml files with Maple.  That is not what I want.
