Underspecification for Frames and FEs.

Frames (elements) can be annotated as underspecified in cases where an annotator cannot decide whether or not to annotate a frame (element) or which of multiple suitable frames (elements) to annotate. To mark a frame (element) as underspecified, select the frame (element) and click strg-u. Underspecified frame (elements) appear in blue color. This default color can be changed under Edit$\Rightarrow$Preferences and Underspecification. See Section 8.3 on how underspecification is coded in the xml files.
