We outline work in progress on extensions to the SiGML no- tation, which is used to describe Sign Language performance at the phonetic level in a manner suitable for animation by a virtual human signer, or signing avatar. These extensions are intended to provide the author or generator of SiGML sign language content with greater flexibility and precision of control, leading to greater authenticity of computer gen- erated performance, while making the production of such content as convenient as possible. A significant influence on our work is the segmental approach to sign language pho- netics of Johnson and Liddell. We illustrate aspects of our approach by means of an example.
