XML Information Set (XML Infoset) is a W3C specification describing an abstract data model of an XML document in terms of a set of information items. The definitions in the XML Information Set specification are meant to be used in other specifications that need to refer to the information in a well-formed XML document.
An XML document has an information set if it is well-formed and satisfies the namespace constraints. There is no requirement for an XML document to be valid in order to have an information set.
An information set can contain up to eleven different types of information items:
- The Document Information Item (always present)
- Element Information Items
- Attribute Information Items
- Processing Instruction Information Items
- Unexpanded Entity Reference Information Items
- Character Information Items
- Comment Information Items
- The Document Type Declaration Information Item
- Unparsed Entity Information Items
- Notation Information Items
- Namespace Information Items
Infoset recommendation Second Edition was adopted on February 4, 2004.

Famous quotes containing the words information and/or set:
“The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge.”
—Charles Sanders Peirce (1839–1914)
“There is no intrinsic worth in money but what is alterable with the times, and whether a guinea goes for twenty pounds or for a shilling, it is ... the labour of the poor and not the high and low value that is set on gold or silver, which all the comforts of life must arise from.”
—Bernard Mandeville (1670–1733)
