// Conditional expression grammar used for HrStringToRestriction()
// lpszString parameter:
// 
// Condition ::=	SimpleCondition						|
//					Condition "|" Condition				|
//					Condition "&" Condition				|
//					"(" Condition ")"					|
//					"!" Condition
//
// "|" is the logical OR operator.
// "&" is the logical AND operator.
// "!" is the logical NOT operator.
//
// Conditional expressions are evaluated from left to right with "|" and "&"
// having equal precedence. "!" is a unary operator that applies to the operand
// to its immediate right.
//
// SimpleCondition ::=	BooleanCondition				|
//						NumericCondition				|
//						StringCondition					|
//						TimeCondition
//
// BooleanCondition ::=	BoolTag "=" BooleanLiteral
//
// NumericCondition ::=	NumericTag "=" NumericLiteral	|
//						NumericTag "#" NumericLiteral	|
//						NumericTag ">" NumericLiteral	|
//						NumericTag "<" NumericLiteral
//
// The meaning of the NumericCondition operators should be evident.
//
// StringCondition ::=	StringTag "=" StringLiteral		|
//						StringTag "#" StringLiteral		|
//						StringTag "}" StringLiteral
//
// "=" is the equality operator.
// "#" is the inequality operator.
// "}" is the contains operator (a "}" b means a contains b).
//
// TimeCondition ::=	TimeTag "=" TimeLiteral			|
//						TimeTag "#" TimeLiteral			|
//						TimeTag ">" TimeLiteral			|
//						TimeTag "<" TimeLiteral
//
// Note that time literals have a resolution of 1 second, so equality and 
// inequality may not be the best conditional tests.
//
// BoolTag ::=		PT_xxx for a property with a boolean (PT_BOOLEAN) value	|
//					"[B" HexNumber "]"
//
// NumericTag ::=	PR_xxxx for a property with a numeric (PT_LONG) value	|
//					"[N" HexNumber "]"
//
// StringTag ::=	PR_xxxx for a property with a string
//                  (PT_STRING8 or PT_UNICODE) value						|
//					"[S" HexNumber "]"
//
// TimeTag ::=		PR_xxxx for a property with a time (PT_SYSTIME) value	|
//					"[T" HexNumber "]"
//
// BooleanLiteral ::=	"0"					|
//						"1"
//
// NumericLiteral ::=	DecimalNumber
//
// StringLiteral ::=	String enclosed in quotes ("xxx").
//
// TimeLiteral ::=		HH:MM{:SS} YYYY-MM-DD (24 hour clock, local time)
//
// DecimalNumber ::= 	DecimalDigit...		|
//						+DecimalDigit...	|
//						-DecimalDigit...
//
// HexNumber ::=		HexDigit...
