  The recently discovered Hilbert space description of renormalizable
interactions of higher spin (equal or bigger than 1) fields requires to replace
the pointlocal s=1 vectorpotentials of indefinite metric (Krein space) BRST
gauge theory by their stringlike counterpart in Hilbert space. It is shown that
the Hilbert space positivity leads to new properties outside the conceptual
range of the gauge theoretic description: topological aspects of Wilson loops,
induced normalization terms (in particular Mexican hat type potentials for
massive vectormesons coupled to Hermitian scalar field) and a possible role of
string-localization in confinerment.
