This function opens the Modify Attributes dialog box for the tag associated with oid if the tag has unspecified required attributes and the requireattrsset option is on, or if the tag has any declared attributes and the promptattrsset option is on.

If oid is not associated with a valid tag, the function returns 0. If the dialog box is not required to be opened, or if the dialog box is opened and is accepted, the function returns 1. If the dialog box is opened and the user cancels, the function returns 0 and the current operation is undone.

This function is useful when a tag needs to be inserted with prompts temporarily turned off, but then later the prompts are desirable.
