Summary: Function to get XML_Memory_Handling_Suite

Initial Comment:
It is not a bug report, it is a feature request. What do 
you think of adding the function, that returns the pointer 
to XML_Memory_Handling_Suite for passed 
XML_Parser? It is necessary for me, I am developing an 
extension for Expat and I would like to use the same 
allocation/reallocation/free function as the current 
XML_Parser uses. Since XML_Parser struct defined 
inside .C-file, I can't get an access to 
XML_Memory_Handling_Suite struct for the parser. 
Please add this function, since it will be very simple.

Sincerely,
 Artyom Bolgar.

Once you set an element declaration handler you need
to free the content model passed to the handler, so
you will need to know the memory handler in use.

It is just a rare case that the code that sets the handlers
has no control over the code that creates the parser.
But it is not too far fetched, so IMO that feature
request makes some sense, unless I am overlooking
the obvious.

Can you explain why you need the memory handler they've
asked Expat to use?  The requirements aren't clear, so more
explanation of the use case should help.

Thanks.

Of course, I know about this. But in my case, I use 
XML_Parser passed by user (and it is created by him), and I 
don't know how it was created, either by 
XML_ParserCreate_MM or not. That is why I requested this 
function.

Are you creating the parser using XML_ParserCreate?
In that case - without supplying an external memory handler,
Expat just uses the standard C runtime functions
malloc, realloc and free.

If you use XML_ParserCreate_MM however, then *you*
are supplying the memory handler yourself.

In both cases you don't need the requested function.

Is your situation different from what I described?
