Here's an example of a sanitizer permitting the pound character that I use: <param name="feature_color" type="color" label="Default feature color" value="#ff00ff"> <sanitizer> <valid initial="string.letters,string.digits"> <add value="#" /> </valid> </sanitizer> </param> Ciao, Eric On 03/10/2016 04:13 PM, Jasper Koehorst wrote: I am creating a tool which allows you to query RDF files.
