Unfortunately the implementation in Mathematica is for numerical
matrices only as the help text states:

SchurDecomposition[m]
yields the Schur decomposition for a numerical matrix m,...

and upper triangular matrices which decompose a given matrix. Any
thoughts on a work around, or is this futile?
