SYNC-SDL-DATAVIEW DEFINITIONS ::=
BEGIN

   MyInteger ::= INTEGER (0 .. 10000)

-- ASN.1 Type definitions must start with an uppercase
-- Field names in records (SEQUENCE) must start with a lowercase
-- Underscores are not allowed: use dash (hyphen) 
-- For integers do not assume that small ranges will be translated to small
-- types in C or Ada (expect unsigned or signed 64 bits types with subtypes
-- for the range in Ada)

-- Simple types:

-- TASTE-Boolean ::= BOOLEAN
-- MyInteger   ::= INTEGER (0..255)
-- MyReal      ::= REAL (0.0 .. 1000.0)
-- MyBool      ::= BOOLEAN
-- MyEnum      ::= ENUMERATED { hello, world, how-are-you }

-- Complex types:

--  MySeq       ::= SEQUENCE {
--      input-data  MyInteger,
--      output-data MyInteger,
--      validity    ENUMERATED { valid, invalid }
--  }
--
--  MyChoice    ::= CHOICE {
--      a BOOLEAN,
--      b MySeq
--  }
--
--  MySeqOf     ::= SEQUENCE (SIZE (2)) OF MyEnum
--
--  MyOctStr    ::= OCTET STRING (SIZE (3))
--
--  -- You can also declare constants
--  myVar       MySeqOf     ::= { hello, world }
