Description
w:u applies underline formatting to the run. It is defined in ECMA-376 Part 1 §17.3.2.40.
The w:val attribute selects the underline style; the optional w:color attribute sets the underline colour independently of the text colour. When w:val="none" the underline is explicitly removed (used to cancel underline inherited from a style).
