The example is here:

http://tools.ietf.org/html/rfc6030#section-7

and contains

   <?xml version="1.0" encoding="UTF-8"?>
   <KeyContainer
       xmlns="urn:ietf:params:xml:ns:keyprov:pskc"
       xmlns:ds="http://www.w3.org/2000/09/xmldsig#";
       xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";
       Version="1.0">
...
       <Signature>
           <ds:SignedInfo>
...

I have validated the example against the schema using xmllint.  The
XMLSec library templates create a Signature element like this:

...
       <ds:Signature>
           <ds:SignedInfo>
...

With the "ds:" prefix on the Signature element, I get a schema
validation error:

    pskctool/tests/pskc-figure9.xml:30: element Signature: Schemas validity 
error : Element '{http://www.w3.org/2000/09/xmldsig#}Signature': This element 
is not expected. Expected is one of ( 
{urn:ietf:params:xml:ns:keyprov:pskc}KeyPackage, 
{urn:ietf:params:xml:ns:keyprov:pskc}Signature, 
{urn:ietf:params:xml:ns:keyprov:pskc}Extensions ).

However, I have come up with a temporary workaround: after
xmlSecDSigCtxSign() succeeds, I do a xmlSetNs (signNode, NULL) to clear
the namespace prefix for the Signature element.  This seems quite ugly
though.  I have yet to write the code to verify these signatures
though...
