You could match on element local-name instead of the full prefixed name, eg.

<template match="*:my-element" />

or, if you need to check the namespace as well:
<template match="*[namespace-uri() =
('urn:iso:std:iso:20022:tech:xsd:camt.054.001.04',
'urn:iso:std:iso:20022:tech:xsd:camt.054.001.08')][local-name() =
'my-element']" />
