Any XML document can be converted to Canonical XML. For example, XML permits whitespace to occur at various points within start tags, and attributes to be specified in any order. Such differences are seldom if ever used to convey meaning, and so these forms are generally considered equivalent < p class a secure 1 < p secure 1 class a In converting an arbitrary XML document to Canonical XML, attributes are encoded in a normative order alphabetical by name , and with normative spacing and quoting. Thus, the second form above would be converted to the first. Canonical XML specifies a number of other details, some of which are the UTF 8 encoding is used line ends are represented using the character 0x0A whitespace ... to Canonical XML is idempotent .

In mathematical logic , an axiom schema plural axiom schemata generalizes the notion of axiom . An axiom schema is a well formed formula formula in the language of an axiomatic system , in which one or more schematic variable s appear. These variables, which are metalinguistic constructs, stand for any First order logic Formation rules term or first order logic subformula of the system, which may or may not be required to satisfy certain conditions. Often, such conditions require that certain variables be free variable free , or that certain variables not appear in the subformula or term. Given that the number of possible subformulas or terms that can be inserted in place of a schematic variable is countably infinite , an axiom schema stands for a countably infinite set of axioms. This set can usually be defined Recursion recursively . A theory that can be axiomatized without schemata is said to be finitely axiomatized . Theories that can be finitely axiomatized are seen as a bit more metamathematically elegant, even if they are less practical for deductive work. Two very well known instances of axiom schemata are the Mathematical induction Induction schema that is part of Peano s axioms for the arithmetic of the natural number s Axiom schema of replacement that is part of the standard ZFC axiomatization of set theory . It has been proved first by Richard Montague that these schemata cannot be eliminated. Hence Peano arithmetic and ZFC cannot be finitely axiomatized. This is also the case for quite a few other axiomatic theories in mathematics, philosophy, linguistics, etc. All theorems of ZFC are also theorems of von Neumann Bernays G del set theory , but the latter is, quite ... to range over all possible properties or relations.

A conceptual schema or conceptual data model is a map of concept s and their Relational model relationships . This describes the semantics of an organization and represents a series of Logical assertion assertion s about its nature. Specifically, it describes the things of significance to an organization entity classes , about which it is inclined to collect information, and characteristics of attributes and associations between pairs of those things of significance relationships . Overview Because a conceptual schema represents the semantics of an organization, and not a database design , it may exist on various levels of abstraction. The original ANSI four schema architecture began with the set of external schemas that each represent one person s view of the world around him or her. These are consolidated into a single conceptual schema that is the superset of all of those external views. A data model can be as concrete as each person s perspective, but this tends to make it inflexible. If that person s world changes, the model must change. Conceptual data models take a more abstract perspective, identifying the fundamental things, of which the things an individual deals with are just examples. The model does allow for what is called Inheritance computer science inheritance in object oriented terms. The set of Instantiation computer science instance s of an entity class may be subdivided into entity classes in their own right. Thus, each instance of a sub type entity class is also an instance of the entity class s super type . Each instance of the super type entity class, then is also ...
