The ITU has recently published some of the SDL standards that came into
force in October 1996.

You can now obtain:

[Z.100 Add.1] Addendum 1 (10/96) to Recommendation Z.100
CCITT Specification and Description Language (SDL)

[Z.106] Recommendation Z.106 (10/96) - Common interchange format for SDL

[Z.110] Recommendation Z.110 (10/96)
Criteria for use of formal description techniques by ITU-T

However, it seems that the ITU still has not published:
a) the methodology supplement to Z.100 (relevant to the use of SDL, MSC and
SDL with ASN.1);
b) MSC-96.
