Q) What is the meaning and syntax of the 'DEF LINE BREAK' directive in FME Plugin Reader Writer metafiles and in which cases should we use it?

A) This affects what types of geometry Workbench will try to write to your DEF lines:

• If this line is GEOM_CHANGE, then Workench will only allow a single geometry per feature type, and will enable the 'Geometry' combo box in the feature type properties dialog.
• If this line is ATTRIB_CHANGE, then Workbench assumes each feature type can handle every geometry type, and will disable the combo box.
• If this line is NO_DEF, Workbench will not write out any DEF lines at all, and the geometry combo box will be disabled.
• If this line contains NO_ATTRIBS, then Workbench will not write any user-defined attributes onto the DEF line.
