Normal Sudoku rules apply.
For accessibility, lines have been marked with an abbreviation to distinguish them as an alternative to the line's colour.
A single line passes through all the regions of the Sudoku grid and is made from smaller sub-lines.
All the 1, 5 and 9 digits can only be placed on the line's corners - Dutch Corners.
Cells connected by a pink Renban [RN] sub-line form a set of consecutive digits, in any order, without repeats.
Adjacent digits along a green German Whisper [GW] sub-line must differ by at least 5.
Box borders divide a blue Region Sum [RS] sub-line into segments with the same sum.
Adjacent digits along a red Parity [PR] sub-line, one digit is odd and the other digit is even.
Along each teal 3 Modular [3M] sub-line, every set of consecutive three digits contains one from the set of {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
The gold [--] sub-lines have no constraints other than their corners (including corners shared with other sub-Lines) being potential Dutch Corners.
Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5.
Not all Xs or Vs are necessarily given.

Revised the wording of the gold [--] line

Nice construction, I was just a little confused by the wording of the rules for gold lines, since it starts with no constraint and the states the corner rule. It may be clearer to restate it, e.g.:
The gold [--] sub-lines have no constraints other than their corners (including corners shared with other sub-Lines) being potential Dutch Corners.
pagedo: @superkinkel - Thanks for your comment. I liked your suggested wording for the gold [--] sub-lines. I changed it to your wording. Thank you.
