Adopts a node from an external document. The node and its subtree is removed from the document it's in (if any), and its `ownerDocument` is changed to the current document. The node can then be inserted into the current document.

Supported since Gecko 1.9 (Firefox 3)

## Syntax

```node = document.adoptNode(externalNode);
```
• `node` is the adopted node that can be used in the current document. The new node's `parentNode` is `null`, since it has not yet been inserted into the document tree.
• `externalNode` is the node from another document to be adopted.

FIXME:

## Notes

In general the `adoptNode` call may fail due to the source node coming from a different implementation, however this should not be a problem with browser implementations.

Nodes from external documents should be cloned using `document.importNode()` (or adopted using `document.adoptNode()`) before they can be inserted into the current document. For more on the `Node.ownerDocument` issues, see the W3C DOM FAQ.

Firefox doesn't currently enforce this rule (it did for a while during the development of Firefox 3, but too many sites break when this rule is enforced). We encourage Web developers to fix their code to follow this rule for improved future compatibility.
