The only thing you could do is figure out a more compact way to store
the strings (e.g., in a char array or even a compressed char array) and
return something other than String from your intern method, like an
integer. IIRC Saxon does something like this internally. So there's even
an open source implementation.
Older versions of Xerces used a similar approach but it was
too difficult to use and, more importantly, maintain. The
decision to use String objects all the way through the system
makes it a lot easier to develop and extend. Having actively
developed in both situations, I prefer the way that it is
now.
The SymbolTable is there as a performance enhancement. And for
most people it works great. Only very rare document instances
would exhibit problems. But even for those, Michael has shown
a workaround, at the expense of speed.
