<li> All structural event callback functions will return an
<code>XML_Status</code> value that the parser will check. This will
allow an application to stop or suspend processing without having to
use <code>setjmp()</code>/<code>longjmp()</code> hackery. </li>
<li> The parser will support suspension of parsing to allow an
application to pause parsing temporarily. A new
<code>XML_Status</code> value, <code>XML_STATUS_SUSPEND</code>, can
be returned by the event callbacks to indicate that Expat should
suspend parsing; the parser will then return from
<code>XML_Parse()</code>, returning <code>XML_STATUS_SUSPEND</code>.
Applications can resume parsing by calling
<code>XML_ParseResume()</code>. </li>
call <code>XML_StopParser</code>, which will therefore become obsolete. </li>
<li> The memory management function signatures will gain an additional
userData-like parameter, so that memory usage can be associated
with a context, allowing usage of memory pools and tracking of memory
usage per parser. The latter could be used to prevent the so-called
"million laughs" DoS attack. </li>
<li> Change how qualified names are reported. Instead of passing one
string where the name parts are separated by a special character, we
are going to use <code>QName</code> structs with members for local name,
namespace URI and prefix. This will apply to element names and attribute
names passed to <code>XML_StartElementHandler</code> and
<code>XML_EndElementHandler</code>. </li>
<li> We will try to add a way of setting additional encodings
by name, using the existing framework built around
<code>XML_UnknownEncodingHandler</code>. </li>
<li> Create different link symbols for different XML_Char sizes.
This would make it possible for different shared libraries making up an
application on linux, to link against expat shared libraries that have
been compiled with different definitions for XML_Char.</li>
