CLDT stands for 'Common Language Data Types'
In IBM Smalltalk there are other abbreviations of that kind:

CLIM  Common Language Implementation
CPM   Common Process Model
CFS    Common File System
CG      Common Graphics Subsystem
CW     Common Widget Subsystems
CP      Common Printing Subsystem
EW     Extended Widget Subsystem

I think CLDT, CLIM, CPM are taken form the ANSI standard.

The documentation for IBM Smalltalk Vs. 6.0 can be downloaded from
IBM Smalltalk Programmers Guide (2.8 MBytes in PDF)
This documentation does not say what is ANSI and what isn't,
so it is possbily not very helpful.

Greetings, Boris
