Query: A CCD vertex deetctor for a high-energy linear e+e- collider   I present a summary of the experience with CCD-based vertex detectors at the
SLD experiment at SLAC, and discuss their advantages for use at a future
high-energy e+e- collider. The extensive R+D programme to improve further the
vertexing capabilities of CCD detectors is also outlined.
