Author XML Documents
What is an XML document?
A basic XML document is simply an XML element that can, but might not, include nested XML elements.
For example, the XML <books> element is a valid XML document:
<books>
<book isbn="0345374827">
<title>Maeve Ascendant</title>
<author>Eva Corets</author>
</book>
</books>
Authoring guidelines
There are some things to remember when constructing a basic XML document.
- All elements must have an end tag.
- All elements must be cleanly nested (overlapping elements are not allowed).
- All attribute values must be enclosed in quotation marks.
- Each document must have a unique first element, the root node.

In the following text box, create an XML document that contains both <element> and <attribute> nodes. Click the Well-formed? button to see whether your XML document conforms to the XML specification.
