Place keynotes on elements in a linked model.

Guidelines for placing keynotes in linked models
Revit LT compares the paths to the keynote files referenced in the current and linked files; it does not compare the keynote tables. If the paths to the keynote files are different, Revit LT assumes that the keynote tables do not match and displays an error message.
If a keynote value is not assigned to the element, a blank keynote is displayed. To edit the keynote value, use the Open (and Unload) command to open the linked file and assign a keynote value to the element.
