A DESCRIPTION OF THE REQUEST :
The java.awt.Desktop.mail() API does only take a URL as parameter.
This is annoying as the mailto URL scheme doesn't define any way to specify an attachment.

JUSTIFICATION :
  To add an attachment to a mail is a common task and the current implementation in mustang misses such a feature.
The most surprising is that the original JDIC API (from where the mail feature comes from) that did allow to add attachment has not been integrated in mustang.
  To integrate the org.jdesktop.jdic.desktop.Message API would be nice to offer more easyness in the mail message description.
