<para><function>glEnableVertexAttribArray</function> enables the
generic vertex attribute array specified by
<parameter>index</parameter>.
<function>glDisableVertexAttribArray</function> disables the
generic vertex attribute array specified by
<parameter>index</parameter>. By default, all client-side
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
