  A basic question for any property of quasi--coherent sheaves on a scheme $X$
is whether the property is local, that is, it can be defined using any open
affine covering of $X$. Locality follows from the descent of the corresponding
module property: for (infinite dimensional) vector bundles and Drinfeld vector
bundles, it was proved by Kaplansky's technique of d\'evissage already in
\cite[II.\S3]{RG}. Since vector bundles coincide with $\aleph_0$-restricted
Drinfeld vector bundles, a question arose in \cite{EGPT} of whether locality
holds for $\kappa$-restricted Drinfeld vector bundles for each infinite
cardinal $\kappa$. We give a positive answer here by replacing the d\' evissage
with its recent refinement involving $\mathcal C$-filtrations and the Hill
Lemma.
