What about:

typedef enum {
	CAIRO_SVG_1_1,
	CAIRO_SVG_1_2
} cairo_svg_version_t;

typedef stuct {
	cairo_svg_version_t id;
	char const *desc;
} cairo_svg_version_info_t;

cairo_svg_version_info_t * cairo_svg_surface_get_version_infos (void);

Which will return a NULL terminated list, and

cairo_surface_t * cairo_svg_surface_create (..., cairo_svg_version_t version_id);
cairo_surface_t * cairo_svg_surface_create_for_stream (..., cairo_svg_version_t version_id);

	Emmanuel.
