How to use empty titles for buttons on the ApplicationBar?

• One of my buttons' icon is a trash can, which should be only titled with "delete" according to WP7's rule, but in fact it's not a "delete" button, and we don't want to change its icon, either. So the only solution seems to be giving it an empty title, which is confirmed to be acceptable by MS. but if I set its Text to empty string, or just leave it as unset, I got an error like "cannot be empty title". So is there a way to set it empty, or just hide the title from users? Many thanks.

  I don't think that your application will fail the marketplace test if you have a different text below the trashcan icon. Having no text (which will not build) or trying to hide this text will be a reason to fail the marketplace test. Personally I need this text in alot of applications to discover what a button actually is doing. My suggestion would be to use a descriptive name for the button and don't worry about the text being the reason to reject your app.
