XMLSec uses the cert from the signed document when it exists. So the
patch I provided builds a verification chain for this cert.

Sorry, I don't understand this idea. The signer's cert should provide
the correct chain i.e. each cert in chain should be correctly signed and
shouldn't be revoked. What's an idea to build chain with signer's cert

Yes, when the signer's cert is in the document, if the CA cert and CRL
are correctly installed, the chain will be built successfully.
