ISSUE-126: DNT-extension syntax includes characters not safe to embed in JSON

DNT-extension syntax includes characters not safe to embed in JSON

State:
CLOSED
Product:
Tracking Preference Expression (DNT)
Raised by:
Roy Fielding
Opened on:
2012-02-15
Description:
The definition of DNT-extension in the FPWD includes a very wide set of characters because we had not made any decisions about extensions. However, if the field-value is going to be echoed back to the client, as in the current proposal for the tracking status resource, then we should reduce the characters allowed to a safe set that can be easily embedded in a JSON string.
