ADsPath SYNTAX
-----------

    ADsPath ::= "ADs" ":" ["//"]
        | Namespace ":" 
        | Namespace "://" ProviderPath
        ;

    Namespace ::= NonEscapedName
        ;
        
    ProviderPath ::= Component
        | Component '/' ProviderPath
        ;

    Component ::= EscapedName
        ;
        
    NonEscapedName ::= ( StringChar)*

    EscapedName ::= ( StringChar | Pair )*
        | '"' ( StringChar | SpecialChars | Pair ) * '"'

    StringChar ::= AllChars - (SpecialChars | '\' | '"')

    Pair ::= "\" ( SpecialChars | '\' | '"' ) 
    
    SpecialChars = '/' | ',' | '<' | '>'


NOTE:

1. Note that the above is a necessary but may not be a sufficient syntactic 
   specification for the ProviderPath. Providers may impose further quoting or 
   escaping rules without violating the above syntax.
   
2. When an entire ADsPath is written in a different context
   as part of another string (for eg., in URLs or search specifications) 
   there is a need to delimit the entire ADsPath. It is recommended that '<' 
   and '>' be used for that purpose. 
   

NOTES FOR THE LDAP Provider:
   
1. the LDAP provider in ADSI defines the syntax of the ProviderPath
   as follows. 
   

    LdapProviderPath ::= [LdapServerName '/'] LdapDN
        ;
        
    LdapDN ::= ADsDN | X500DN
    
    ADsDN ::= LastComponent
        | Component '/' ProviderPath
        ;
        
    X500DN ::= LastComponent
        | Component ',' ProviderPath
        | Component ';' ProviderPath
        ;
        
    LastComponent ::= FullComponent ',' ClassSpecifier
        | Component
        ;
        
    FullComponent ::= ClassSpecifier '=' Component
        
    Component ::= EscapedName
        ;
        
    ClassSpecifier ::= <non x500 name>
        ;

    EscapedName ::= ( StringChar | Pair )*
        | '"' ( StringChar | SpecialChars | Pair ) * '"'

    StringChar ::= AllChars - (SpecialChars | '\' | '"')

    Pair ::= "\" ( SpecialChars | '\' | '"' ) 
    
    SpecialChars = '/' | ',' | '<' | '>' | ';' | '='
