++<dd>
++Added in Expat 2.6.0.
++Include support for
++<a href="https://www.w3.org/TR/2006/REC-xml-20060816/#sec-physical-struct">general entities</a>
++(syntax <code>&amp;e1;</code> to reference and
++syntax <code>&lt;!ENTITY e1 'value1'&gt;</code> (an internal general entity) or
++<code>&lt;!ENTITY e2 SYSTEM 'file2'&gt;</code> (an external general entity) to declare).
++With <code>XML_GE</code> enabled, general entities will be replaced by their declared replacement text;
++for this to work for <em>external</em> general entities, in addition an
++<code><a href="#XML_SetExternalEntityRefHandler">XML_ExternalEntityRefHandler</a></code> must be set using
++<code><a href="#XML_SetExternalEntityRefHandler">XML_SetExternalEntityRefHandler</a></code>.
++Also, enabling <code>XML_GE</code> makes
++the functions <code><a href="#XML_SetBillionLaughsAttackProtectionMaximumAmplification">
++XML_SetBillionLaughsAttackProtectionMaximumAmplification</a></code> and <code>
++<a href="#XML_SetBillionLaughsAttackProtectionActivationThreshold">
++XML_SetBillionLaughsAttackProtectionActivationThreshold</a></code> available.
++<br/>
++With <code>XML_GE</code> disabled, Expat has a smaller memory footprint and can be faster, but will
++not load external general entities and will replace all general entities
++(except the <a href="https://www.w3.org/TR/2006/REC-xml-20060816/#sec-predefined-ent">predefined five</a>:
++<code>amp</code>, <code>apos</code>, <code>gt</code>, <code>lt</code>, <code>quot</code>)
++with a self-reference:
++for example, referencing an entity <code>e1</code> via <code>&amp;e1;</code> will be replaced
++by text <code>&amp;e1;</code>.
