-/* Pool support. For efficiency, map_html_tags() stores temporary

+/* Pool support. A pool is a resizable chunk of memory. It is first
+ allocated on the stack, and moved to the heap if it needs to be
+ larger than originally expected. map_html_tags() uses it to store
+ the zero-terminated names and values of tags and attributes.
+
+ Thus taginfo->name, and attr->name and attr->value for each
+ attribute, do not point into separately allocated areas, but into
+ different parts of the pool, separated only by terminating zeros.
+ This ensures minimum amount of allocation and, for most tags, no
+ allocation because the entire pool is kept on the stack. */
