Spectroscopy of three QSOs with complex, high-ionization absorption is presented. The QSOs belong to the broad absorption-line class of QSOs and exhibit absorption troughs with considerable structure. The nature of the broad absorption is discussed by considering the consequences of the generally accepted models for the broad emission-line region. It is shown that the broad absorpton-line clouds are incapable of giving rise to all of the observed broad emission lines, particularly Mg II. Therefore, if the broad absorption-line region gives rise to observable emission, the generally adopted models for the emission-line region are incorrect. A two (or more) component model for the broad emission/absorption-line region cannot be ruled out. A high-ionization outer component could conceivably give rise to broad absorption lines and some broad high-ionization emission lines. Alternatively, the broad absorption-line region may lie well beyond, and be separate and distinct from, the broad emission-line region.
