1. A completion system, comprising: an intermediate assembly for location between an upper completion and a lower completion, the intermediate assembly having a barrier valve transitionable between an open position and a closed position, the intermediate assembly further including a packer device for isolating the borehole, anchoring the intermediate assembly, or a combination including at least one of the foregoing; andthe upper completion being a production string, run in with a removable plug, the plug for enabling the packer device of the intermediate assembly to be set by pressurizing fluid against the removable plug the upper completion, the upper completion being operatively coupled with the barrier valve for mechanically transitioning the barrier valve to the closed position in response to the upper completion being withdrawn from the lower completion. 2. The completion system of claim 1, wherein mechanical movement of the upper completion also enables the upper completion to transition the barrier valve to the open position. 3. The completion system of claim 1, wherein the upper completion includes a stroker that is actuatable by fluid pressure for mechanically moving the barrier valve between the open and closed positions. 4. The completion system of claim 1, wherein the lower completion includes at least one assembly for enabling stimulation, hydraulic fracturing, frac packing, gravel packing, or a combination including at least one of the foregoing. 5. The completion system of claim 1, wherein the upper completion string includes a shifting tool that extends through the packer device for engagement with the barrier valve. 6. The completion system of claim 1, further comprising a subsequent intermediate assembly stacked with the intermediate assembly, the subsequent intermediate assembly having a subsequent barrier valve. 7. The completion system of claim 6, wherein the intermediate assembly is engaged between the subsequent intermediate assembly and the lower completion and the subsequent intermediate assembly is engaged between the intermediate assembly and the upper completion string. 8. The completion system of claim 1, wherein the production string comprises an artificial lift system. 9. A completion system, comprising: an intermediate assembly for location between an upper completion and a lower completion, the intermediate assembly having a barrier valve transitionable between an open position and a closed position;a subsequent intermediate assembly stacked with the intermediate assembly, the subsequent intermediate assembly having a subsequent barrier valve, the intermediate assembly being engaged between the subsequent intermediate assembly and the lower completion and the subsequent intermediate assembly being engaged between the intermediate assembly and the upper completion;wherein the upper completion includes a first tool operatively arranged for enabling the subsequent barrier valve to transition between open and closed positions and the subsequent intermediate assembly is arranged with a second tool for holding the barrier valve in its open position while the subsequent intermediate assembly is engaged with the first intermediate assembly. 10. A method of operating a completion system, comprising: withdrawing an upper completion, the upper completion operatively coupled to a barrier valve, that is part of intermediate assembly located between a lower completion and the upper completion, for controlling operation of the barrier valve; andclosing the barrier valve mechanically due to the withdrawing:wherein the upper completion string includes a removable plug, and the method further comprises pressurizing against the removable plug for setting a packer device of the intermediate assembly and removing the removable plug. 11. The method of claim 10, further comprising: running in the upper completion or a subsequent upper completion; andopening the barrier valve mechanically due to the running in. 12. A method of operating a completion system, comprising: withdrawing an upper completion, the upper completion operatively coupled to a barrier valve for controlling operation of the barrier valve; andclosing the barrier valve mechanically due to the withdrawing,the method further comprising stacking a subsequent intermediate assembly on the intermediate assembly, the subsequent intermediate assembly having a subsequent barrier valve and holding the barrier valve of the intermediate assembly in the open position, the upper completion being operatively engagable with the subsequent intermediate assembly for transitioning the subsequent intermediate assembly between open and closed positions. 13. The method of claim 10, wherein the barrier valve is part of a lower completion. 14. The method of claim 10, further comprising running the barrier valve in on the upper completion. 15. The method of claim 10, wherein the upper completion is a production string.
