> In a schema, a previously defined schema may be referenced by name. The way
> the implementation tracked this was a look-aside mapping of name to instance.
> If a symbol node was encountered during parsing it was referenced via the
> map.
> Instead of using a look-aside map, now a pointer to the referenced node is
> stored in the symbolic schema node, so while parsing it may be de-referenced
> without a lookup. The look-aside map is only when compiling the schema, so
> that symbols are resolved at compile time.
> This improves performance, reduces storage space, and simplifies some some
> upcoming changes (resolving schema differences).
