While an XML file might conform to the XML specification, it might not be a valid form of a particular dialect.An XML schema lets you verify that certain elements are present, while making sure that the values presented are of the correct type.The full XML specification can be read here, although, as we'll see shortly, .NET gives you the tools to write valid XML automatically.We can see clearly that there is a catalogue containing CDs, each of which contains some tracks (music aficionados will notice that I have cut down the track listings for space! You can also see that XML can be less efficient than some other file formats.

We define a namespace using an xmlns declaration, followed by the prefix, which is equal to a URI that uniquely identifies the namespace: Parsers can now recognise both meanings of "film type" and handle them accordingly.For example, XML 1.0 requires that all XML files consist of one root element; that is, a single element contains all other elements.In our music library example above, catalog is our root element, as it contains all our other elements.Sometimes, it doesn't make sense for information to appear between opening and closing tags.For example, if we need more than one piece of information to describe an element, we might like to include those multiple pieces of information within a single tag.

To start using XML effectively, a sound knowledge of its terminology and file structures needs to be gained.
