> Imagine we have a schema with a compex element that has all optional children and data where the none of the children exist. Or a similar case where all the children of a complex element are hidden. In such cases, the XMLTextInfosetOutputter will output something like this:
> {code:xml}
> <root>
>   <complex_with_no_children>
>   </complex_with_no_children>
> </root>
> {code}
> To a non-schema aware XML parser, complex_with_no_children will look like a simple type with whitespace content instead of an empty complex type, which can cause problems.
> Instead, the XMLTextInfosetOutputter should detect when a complex element will not have any text output (i.e. no children, or all children are hidden), and instead output an element with no content , so the above should look more like:
> {code:xml}
> <root>
>   <complex_with_no_children />
> </rot>
> {code}
