<XML> property of an element

NOTE 1 to entry It is additional information about a piece of data (element). Often attributes are used to pass information about the element and hence can be said to provide metadata for the element. An attribute is a value indicator (=) and the attribute value is specified within the tag (i.e. <H3 align=""centre"">). Attribute in XML is a name=""value"" pair that can be placed in the start tag of an element. For XML, all values have to be quoted with single or double quotes.
