Comment (by kitchin):

 Another use case, besides css selectors, is the comparison operator ">".
 Since the WP API functions allow it as a parameter when searching for
 posts (via the WP_Meta_Query parameter "meta_compare"), it is conceivable
 a plugin author would allow it in a search shortcode attribute. Perhaps
 the plugin could handle it escaped, but if we're escaping `[`, `]`, why
 escape `<`, `>` ?
