  Recently, the most general theory of electromagnetism invariant under duality
and conformal invariance was written, and dubbed ModMax. It arises from a
generalization of Born-Infeld (BI) theory by taking the infinite tension limit,
$T\rightarrow\infty$. In this note we show that this generalization can be
obtained from a brane-like construction, just like BI, and can thus be coupled
to scalars in the same way to obtain a DBI-like action. All the BIon and
catenoid solutions, and their interpolations, are still solutions of the
generalized DBI-like action, suggesting that an interpretation within string
theory could be possible. We also show that Ra\~nada's knotted solutions (with
nonzero helicities) are still valid, both in the ModMax theory, and in its
precursor.
