Concrete and global syntax properties

You can set concrete syntax properties on different types and elements. Some properties apply to more than one type or element of the abstract syntax. You can also set two global language properties in the concrete syntax. These properties are not attached to a particular abstract syntax type.

Concrete syntax properties for types and element

The following table shows all the properties that are available in the concrete syntax, and the types and elements to which they apply.

Global properties

Neither of these properties are attached to a particular type of the abstract syntax, so they are not prefixed with a type name:

  • semanticContextExtension

  • translatorClass

If you want to use alternate names in the choice lists, set the useAlternateNames property to the following in the concrete syntax: 

useAlternateNames = true.
