@b.gatessucks I tried to account for that possibility by passing it through IntegerPart (discussed in my question), but that did not help. How can I fix this issue?

comment Using Functions as Arguments to Function
Yes but as I said above I need to have MyNorm'[{x,y,z}] evaluate to Dt[myNorm[{x, y, z}], t]

comment Using Functions as Arguments to Function
While this does give the derivative of the norm function, when I attempt deriving myNorm[r[t]] where r[t] is a piecewise parametric function in three parts {x[t], y[t], z[t]}, it still returns an error message.
