[det]xmld_signed_DOM(+DOM, -SignedDOM, +Options)

Translate an XML DOM structure in a signed version. Options:

key_file(+File): File holding the private key needed to sign
key_password(+Password): String holding the password to op the private key.

The SignedDOM must be emitted using xml_write/3 or xml_write_canonical/3. If xml_write/3 is used, the option layout(false) is needed to avoid changing the layout of the SignedInfo element and the signed DOM, which will cause the signature to be invalid.
