ASN.1 doesn't constrain representation, it's purely an Abstract Syntax 
Notation - it lists what information content something has, and nothing more.

Element ::= {
	name QName,
	attributes SEQUENCE OF SEQUENCE {
		name QName,

	comment UTF8String,
	processInstruction ProcessingInstruction,
	cdata UTF8String
