+
+  DEPEX (DEPendency EXpresion) BNF Grammer for PEI:
+  The BNF grammar is thus:
+<pre>
+     <depex>   ::= <bool>            
+     <bool>    ::= <bool> and <term> 
+                 | <bool> or <term>  
+                 | <term>            
+     <term>    ::= not <factor>      
+                 | <factor>          
+     <factor>  ::= <bool>            
+                 | <boolval>         
+                 | <depinst>         
+                 | <termval>         
+     <boolval> ::= true              
+                 | false             
+     <depinst> ::= push GUID
