    3333    These groups will be studied when attempting to decompose 
    3434    these special exceptions. This is as accurate as it can be, 
    35     but it is not foolproof. 
     35    but it is not foolproof. Passing a groupNamePrefix that 
     36    defines a prefix that all referenced kerning groups will 
     37    start with. If this is known, it will help remove the 
     38    ambiguities described above.
