IDOM memory management

["Houle, Dennis W" <De...@West.Boeing.com>]

Team Xerces-C,
As I understand memory management in IDOM, the IDOM_Document allocates heap
memory for XMLCh* returned from such methods as IDOM_Element::getAttribute
and does not deallocate heap memory until the IDOM_Document destructor is
called.

So does this mean that the heap will grow unbounded if
IDOM_Element::getAttribute is called repeatedly?

Thanks much.

Not really.  Normally the getAttribute just return the same text value that is
already saved inside the node.  It doesn't allocate a new memory for the XMLCh*
returned.
