EnablePreserveTaggedText configuration parameter (TDK)
Syntax (prefix with dash in a Generation Settings Scheme):
EnablePreserveTaggedText=0 or 1
When set to 1, the EnablePreserveTaggedText configuration parameter ensures that text within markers in the SDL files is not overwritten, even if the associated generation template text is changed in the model.
When enabled, before overwriting an SDL file the text within markers in the code file is copied and after generating the new code file, the copied text is pasted within the appropriate markers within the SDL file.
For TDK Code Generation Transformation Patterns models, do not set EnablePreserveTaggedText to 1.
