XQuery Question:

TC Trustcenter Publisher ID is needed if you want to get your application Symbian Signed (freeware developers excluded). Publisher ID identifies you as the source of the application. Before submitting the application to Symbian Signed, you need to sign it with a Publisher ID. The test house checks the signature and verifies that the application hasn’t been tampered with on the way to Symbian signing and that the application is coming from you.
