A shoulder tag is fine, but it should be added as a sub tag of the main 
highway=* such as shoulder=yes/no & shoulder_width=* etc.

It should not be associated with bicycle=* or cycleway=*. If it's a 
shoulder then vehicles can enter it.

If there's a lane at the side of the road designated for bikes then it's 
not a shoulder.

Take a look at this for relevant  examples:
