The latch of claim 1, wherein the pawl is movable along the longitudinal axis when the pawl drive interface moves between the drive position and the disconnect position. 3. The latch of claim 2, wherein the pawl is spaced further from the rear side of the tray when the pawl drive interface is in the drive position as compared to the disconnect position. 4. The latch of claim 3, further including a compression spring member disposed between the tray and the pawl for urging the pawl drive interface toward the drive position. 5. The latch of claim 4, wherein the rotary member includes a shaft and a disconnector attached to the shaft, the disconnector including a drive interface for selectively engaging the drive interface of the pawl to rotate the pawl when the rotary member is disposed in the second position if the pawl drive interface is in the drive position. 6. The latch of claim 5, wherein the compression spring member comprises a first compression spring member, the latch further including a second compression spring member disposed between the tray and the disconnector for urging the disconnector away from the rear side of the tray. 7. The latch of claim 1, further including a handle pivotally mounted to the rotary member on the front side of the tray, the handle movable between a first position and a second position to thereby move rotary member along the longitudinal axis between its respective first and second positions, the rotary member being rotatable via the handle when the handle is in the second position. 8. The latch of claim 7, wherein the pawl includes a stop interface for preventing rotation of the pawl when the handle is not in the second position. 9. The latch of claim 8, further including a stop interface attached to the tray for selectively engaging the stop interface on the pawl when the handle is not in the second position. 10. The latch of claim 1, wherein the locking device includes a locking cylinder and a locking bar, the locking cylinder selectively positioning the locking bar between a locked position and an unlocked position. 11. The latch of claim 10, wherein the locking bar has a lock interface for preventing movement of the pawl drive interface from the disconnect position to the drive position when the locking bar is in the locked position. 12. The latch of claim 11, wherein the pawl has a lock interface for selective engagement by the locking bar lock interface. 13. The latch of claim 1, wherein the rotary member and the pawl are configured to function as a compression latch. 14. The latch of claim 13, wherein the pawl drive interface is movable along the longitudinal axis between the drive position and the disconnect position, and wherein the pawl drive interface is spaced further from the rear side of the tray when in the drive position as compared to the disconnect position, a compression spring member being disposed between the tray and the pawl for urging the pawl drive interface toward the drive position. 15. The latch of claim 14, further including a handle pivotally mounted to the rotary member on the front side of the tray, the handle movable between a first position and a second position to thereby move rotary member along the longitudinal axis between its respective first and second positions, the rotary member being rotatable via the handle when the handle is in the second position. 16. A rotary actuation latch with disconnect feature, the latch comprising: a tray for attachment to one of a door or a frame, the tray having a front side and a rear side; a handle assembly rotatably mounted to and extending through the tray, the handle assembly being movable along a longitudinal axis relative to the tray between a first position and a second position; a pawl disposed on the rear side of the tray for engaging the other of the door or the frame for securing the door in a closed position, the pawl being selectively connectable or disconnectable for rotation via the handle assembly; and a locking device attached to the tray and movable between a locked position and an unlocked position, the locking device when in the locked position disconnecting the pawl from rotation via the handle assembly while not preventing the handle assembly from moving along the longitudinal axis between the first and second positions or from rotating around the longitudinal axis when in the second position. 17. The latch of claim 16, wherein the pawl is movable along the longitudinal axis for the selective connection or disconnection for rotation via the handle assembly, a compression spring member disposed between the tray and the pawl urging the pawl toward the selective connection. 18. The latch of claim 17, wherein the locking device when in the locked position prevents the pawl from moving toward the selective connection to thereby disconnect the pawl from rotation via the handle assembly. 19. The latch of claim 16, wherein the handle assembly, the pawl, and the tray are configured so that the handle assembly can not rotate around the longitudinal axis when the handle assembly is in the first position. 20. A rotary actuation compression latch with disconnect feature, the latch comprising: a tray for attachment to one of a door or a frame, the tray having a front side and a rear side; a handle assembly rotatably mounted to and extending through the tray, the handle assembly being movable along a longitudinal axis relative to the tray between a first position and a second position; a pawl disposed on the rear side of the tray for engaging the other of the door or the frame for securing the door in a closed position, the pawl being rotatable via the handle assembly between a latched and an unlatched position, the handle assembly and pawl cooperating to provide a compression latching function along the longitudinal axis; a locking device attached to the tray and movable between a locked position and an unlocked position; and means for disconnecting the pawl from rotation via the handle assembly while maintaining the compression latching function when the locking device is in the locked position while not preventing the handle assembly from moving along the longitudinal axis between the first and second positions. 21. The latch of claim 20, wherein the means for disconnecting includes a locking interface disposed on the locking device and the pawl for preventing the pawl from rotating with the handle assembly when the locking device is in the locked position. 22. The latch of claim 21, wherein the pawl is movable along the longitudinal axis, and the locking interface precludes movement of the pawl along the longitudinal axis when the locking device is in the locked position. 23. The latch of claim 20, where the means for disconnecting includes a drive interface disposed on the pawl and the handle assembly engageable when the handle assembly in the second position and the locking device is in the unlocked position to thereby allow rotation of the pawl via the handle assembly. 24.
