Feature string syntax
The feature string must be 11 characters long for FileMaker Pro
plug-ins.
The first four characters of the feature string are the ID of the
FileMaker Pro plug-in. The ID must be unique for each plug-in and
must not begin with “
F,” “FM,” or “Web.” For the Mac OS, it is
recommended that you set the creator type of the plug-in to this same
value. The ID can only contain low-ASCII alphanumeric characters
(such as
0-9, A-Z, and a-z).
Note So that there will be a good chance of having a unique ID, you
should register the ID at the Apple Developer Support web site—
even if you won’t be creating a Mac OS version of your plug-in. To
register plug-in IDs, go to the developer support pages on the Apple
Computer web site at www.filemaker.com/developers/index.html
(see “Registering your plug-ins” on page 10-13).
