The present invention relates to a compound of formula I and a process for making: . The output shaft assembly carries a pawl which pivots on the output shaft assembly between two positions, one permitting driven rotation of an output shaft of the output assembly in a clockwise direction, and the other permitting driven rotation in a counterclockwise direction. The imidazolium salt preferably has the general structure ofwherein X\u2296 is a counter ion and R1, R2, R3, R4, and R5 are independently selected from the group consisting of C1-C6 hydrocarbon substitutes. A secondary XML processing agent can transform the hidden source into a readable form, which is consumable by the primary processing agent.
