AIUI, the GS mark is a 'private' mark, with no statutory significance.
If so, the proprietors of the mark can require anything they like, even
a pond of flesh, if they so choose.

Indeed, but in which order?

Equally, if you do EMC first and then have to make changes to achieve a
safety 'pass', you may have to go back and do EMC again.

See above.

I agree in principle. But 'approval' is not correct in the context of CE
marking. There is no third-party approval involved, for almost all
products. The manufacturer has to sign the DOC and the DOC has to be
true. The manufacturer uses the test-house reports to satisfy himself
(and any regulatory authority that challenges the product's conformity)
that the DOC is true.

I support your position.

Tomorrow, I may have an opportunity to ask some people who are in a
position to give authoritative advice on this matter. If so, I'll
respond on Saturday.

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.
