Do you mean the name of the string option, like "fax:number"? I do not 
know whether a CUPS option name van contain a colon, probably not due to 
the colon's special meaning in PPD files. Or do you mean the content of 
the string should start with "fax:", like "fax:001-218-555-7777"? It 
would be awkward if the user had to type "fax:" before he types the 
number. We expect the user to type only the number ("001-218-555-7777"), 
then CUPS gets something like "faxnumber=Custom.001-218-555-7777".
