Schema for XSLT 1.0 Recommendation, http://www.w3.org/TR/1999/REC-xslt-19991116
Using XML Schema CR Drafts, 

- Part 1, http://www.w3.org/TR/2000/CR-xmlschema-1-20001024/

This work is a product of the W3C XML Schema WG Task Force for authoring schema 
for W3C Recommendations as an illustration of the XML Schema Language. This schema
is illustrative and non-normative. Internal names created by this schema follows the
same convention used by XSLT 1.0 specification.

Comments were stolen from the XSLT 1.0 specification, 
	http://www.w3.org/TR/1999/REC-xslt-19991116#element-syntax-summary

Asir intends to update this schema as the XML Schema drafts advance from CR to 
PR and then REC. Expected changes are,

[1] XML Schema Namespace URI
[2] Change attribute declaration syntax


KNOWN ISSUES,

(a) XML Schema Definition Language cannot capture a unique wild card expression in XSLT:
"In addition, the xsl:stylesheet element may contain any element not from the XSLT namespace,
provided that the expanded-name of the element has a non-null namespace URI" -
http://www.w3.org/TR/1999/REC-xslt-19991116#stylesheet-element (This will not be an issue as per XML Schema PR)

		<!-- 	There are three ways that you can construct a 
				schema for XSLT stylesheets that create instances of a 
				particular result structure

				(a)	Declare all your result elements as a member of 
					xsl:result-element substitution group

				(b) Redefine model group xsl:result-element to accomodate
					the desired structure

				(c)	Do nothing. This schema is designed to allow any element node
					or nodes if they have any namespace other than the XSLT 
					namespace or not namespace qualified

				I recommend (a) or (b)
				In addition, I added a an attributeGroup util, 'result-element' 
				for your convenience
