Rules of 'XV Sudoku'

Place numbers in the grid such that each row, column and 3x3 box contain the numbers 1 to 9. All adjacent cells with two digits summing to 5 are marked by V, while those summing to 10 are marked by X. The cells edges which do not contain an X or a V cannot have digits summing to 5 or 10.
