XML Security Library Structure.In order to provide the an ability to use different crypto engines, 
	the XML Security Library is splitted in two parts: core library (xmlsec)
	and crypto library (xmlsec-openssl, xmlsec-mscrypt, xmlsec-gnutls, 
	xmlsec-gcrypt, xmlsec-nss, ...).
	 The core library has no dependency on any crypto library and provides 
	implementation of all the engines as well as support for all the non 
	crypto transforms (xml parser, c14n transforms, xpath and xslt 
	transforms,...). The XML Security Crypto library provides 
	implementations for crypto transforms, crypto keys data and key 
	data stores. Application is linked with particular XML Security 
	Crypto library (or even libraries), but the actual application 
	code might be general enough so switching crypto engine would be 
	a matter of changing several #include directives. |
