[xmlsec] Signing a document with key and cert..

I'm trying to create signed xml documents and verify that they are correctly 
signed, but I'm having trouble.

Using the xmlsec examples, I am able to create signed documents, but they all 
fail when I paste them into the online verifier (I guess when it works there, I 
am ready to try to do the same locally). I understand that any unsigned key will 
probably not be verified correctly, so I downloaded the "fake" root cert and 
corresponding private key. I further signed my local private key using the 
"fake" root cert.

So far I have not been able to find an example on how to use my key AND the 
cert. An old posting from Aleksey mentions using 
"xmlSecSimpleKeyMngrAddCertToKey, but I can find no such function. I have also 
tried loading the key first, then the cert into the same keysmngr using 
SimpleKeysMngrLoadPemKey followed by a SimpleKeysMngrLoadPemCert, but I am not 
sure whether this means that the cert will be used when signing (if I try to 
validate a document after loading the key and cert, it will still not be 
verified with the online verifier). I have also tried putting the key and cert 
into the same file and load it with *LoadPemKey, but still no luck.

Does anybody have an example on what needs to be done to create a signed 
document that can be verified with the online verifier, or any hints on what 
needs to be done?
