+As in Example \ref{ex:bord-cat}, for $X$ a $k$-ball, $k<n$, we define $\Bord^{n,\infty}(X)$
+to be the set of all $k$-dimensional
+submanifolds $W$ of $X\times \Real^\infty$ such that the projection $W \to X$ is transverse
+to $\bd X$.
+For an $n$-ball $X$ with boundary condition $c$ 
+define $\Bord^{n,\infty}(X; c)$ to be the space of all $k$-dimensional
+submanifolds $W$ of $X\times \Real^\infty$ such that 
+$W$ coincides with $c$ at $\bd X \times \Real^\infty$.
+(The topology on this space is induced by ambient isotopy rel boundary.
+This is homotopy equivalent to a disjoint union of copies $\mathrm{B}\!\Homeo(W')$, where
+$W'$ runs though representatives of homeomorphism types of such manifolds.)
