There is a whitespace between the font-format and font-tech function names and their opening parenthesis:

<supports-font-tech-fn> = font-tech ( <font-tech> )
<supports-font-format-fn> = font-format ( <font-format> )

These definitions correspond to the font-tech or font-format keyword followed by a simple block containing <font-tech> or <font-format>, instead of the corresponding functions containing these types.
