ch entry may specify a single type or consist of a comma separated list of types, with any
 leading or trailing white-spaces in a single type entry being ignored. For example:

 <pre>
 { "image/jpeg, image/gif ", " image/png" }
 </pre>

 Use of the comma-separated form allows definition of a common string constant for use on multiple targets.</div>
