Since the template is just an XML file, it might be created in advance 
	and saved in a file. It's also possible for application to create 
	templates without using XML Security Library functions. Also in some 
	cases template should be inserted in the signed or encrypted data 
	(for example, if you want to create an enveloped or enveloping 
	signature).
Signature verification and data decryption do not require template 
	because all the necessary information is provided in the signed or 
	encrypted document.
