Customizing the metamodel : Keywords for USRPROPS : COPY PROPERTIES FROM
  
COPY PROPERTIES FROM
This command enables you to copy properties into the current definition type from other definition types. It enables you to consolidate similar concepts into a single definition type. This applies to definitions only.
Syntax
DEFINITION <object-1>
{
...
COPY PROPERTIES FROM <object 2> {[, <object n>]}...
Example
DEFINITION "Elephant"
{
...
COPY PROPERTIES FROM "Change Request"
COPY PROPERTIES FROM "Dependency", "Node"
...
}
The copy is performed at that point in the input where the copy statement is encountered. If, in the above example, properties are added to Change Requests, Dependencies or Nodes later in the property file(s), or existing properties are changed later in the property file(s), the additions and changes are not copied.
Notes
1 Where properties already exist they are not replaced.
2 The chapter and group structure is also copied and merged into the target.
