Fragment instead of query in signal discovery requests

[UlfBj]

• Current syntax for a signal discovery request is ** GET Vehicle/Drivetrain/FuelSystem?$spec=0
• Proposed syntax GET Vehicle/Drivetrain/FuelSystem#$spec To get the full tree below GET Vehicle/Drivetrain/FuelSystem?$searchEQ.#$spec To get two levels
• RFC 3986 “The query component contains non-hierarchical data that, along with data in the path component, serves to identify a resource within the scope of the URI's scheme and naming authority” “The fragment identifier component of a URI allows indirect identification of a secondary resource by reference to a primary resource and additional identifying information.”
