No.

At the beginning of an external entity other than the document
(main) entity, it is correct but not required to use a text
declaration.  This looks similar to an XML declaration, but with
the following differences:

	The encoding declaration part is required.

	The standalone declaration part is forbidden.

That is exactly why it is permitted.
