    generic vertex attribute array specified by

    <function>glDisableVertexAttribArray</function> disables the
    generic vertex attribute array specified by

    capabilities are disabled, including all generic vertex
    attribute arrays. If enabled, the values in the generic vertex
    attribute array will be accessed and used for rendering when
    calls are made to vertex array commands such as
