To be more accurate: this is the internal structure related to the
DTD (and internal subset) that should be cached (to be reused when
the DTD with internal subset is the same, thus not taking additional
memory when a second document is processed).

Well, it is important on machines that don't have enough memory.

By caching the DTD structures, one could gain something like a
factor 1000 on the asymptotic memory usage with small documents
(3 KB vs 3 MB for the DTD itself). This is quite significant.
