We have tried to keep the vocabulary in this document strictly defined. For example, each data type has a unique name. That name is not used with any other meaning in this document.
This document does not include a glossary, since any description of the terms used would simply repeat the description of the language feature. Please check the table of contents for any term which is unfamiliar, since most terms important to SDL have their own section.
Three-dimensional coordinates and directions are specified using the x,y,z system, corresponding to the system used by the modeler.
Reserved words are printed in bold.
