/**
* Represents a minimal document object that has no parent. It is used as a
* light-weight version of Document to store well-formed or potentially
* non-well-formed fragments of XML.
*
* Various other methods can take a document fragment as an argument (e.g.,
* any Node interface methods such as Node.appendChild and Node.insertBefore),
* in which case the children of the fragment are appended or inserted, not
* the fragment itself.
*
* This interface is also of great use with Web components: <template>
* elements contains a DocumentFragment in their HTMLTemplateElement::$content
* property.
*
* An empty DocumentFragment can be created using the
* Document::createDocumentFragment() method or the constructor.
* @property ?string $innerHTML Gets the HTML serialization of the element's descendants (read only).
* @property string $innerText Represents the "rendered" text content of a node and its descendants.
