In my cshlp files, there is a <helpfileUID> field.

The SDK manual says :

helpfileUID
The helpfileuid tag contains the UID of the help file to be generated. This is used so that Symbian OS can merge help files even if they have the same name.

<helpfileUID>UID</helpfileUID>
Note
This UID is not the same as the UID used in the source RTF file—which belongs to the application
Is this UID another ID that we should get from symbian signed? At the moment, we use the same one for 3rd and 2nd edition, and I think it's just been picked 'at random'.

Can it be the same as the UID in the pkg file (which isn't shared by any application)?

Max.
