"Access 2007 Bible"

In
other words, XML provides dynamism to both data and metadata.
An XML tag is also known as an element.
Dataare information describing something, such as a person??™s name. Metadata
describes data, such as how long a person??™s name can be, and that it must be a string
and not a numeric value. In an Access application, the metadata associated with a field in a table
include the name applied to the field, its data type, and the maximum length applied to the field.
Data, of course, are the values stored within the field.

Using XML in Access 2007 37
One thing that is relatively difficult for some people to understand is that an XML document
includes very few predefined tags. Unlike HTML, where every tag is defined by a specification,
XML tags are completely variable. There are one or two exceptions, such as the tag.
Otherwise, almost anything goes, as long as the tags follow a few basic rules. The only restrictions
applying to XML are as follows:
n Every opening tag must have a corresponding closing tag.
