<newElementContent addRequiredAttributes = boolean : true emptyAttributes = boolean : false generateIds = boolean : false addChildElements = (none|firstChoice|simplestChoice) : simplestChoice />
Parametrizes the content of a newly inserted element automatically generated by XXE (has no effect on element templates):
Example:
<!ELEMENT anchor EMPTY> <!ATTLIST anchor id ID #REQUIRED>
addRequiredAttributes="false" creates <anchor/> (emptyAttributes and generateIds are ignored in such case) .
addRequiredAttributes="true", emptyAttributes="false", generateIds="false" creates <anchor id="???"/>.
addRequiredAttributes="true", emptyAttributes="true", generateIds="false" creates <anchor id=""/>.
addRequiredAttributes="true", generateIds="true", creates <anchor id="__f34a62b09.b"/> (whatever is the value of emptyAttributes).
Example:
<!ELEMENT item ((title,definition,body)|description)>
addChildElements="none" creates <item></item> (which is invalid).
addChildElements="firstChoice" creates <item><title></title><definition></definition><body></body></item>. This option is useful for DTD or XML Schema authors who need to precisely control how XXE automatically generates newly inserted elements.
addChildElements="simplestChoice" creates <item><description></description></item>.
Example:
<newElementContent generateIds="true" addChildElements="firstChoice" />
