136-761: Is a stub . You can help Misplaced Pages by expanding it . Canonical XML Canonical XML is a normal form of XML , intended to allow relatively simple comparison of pairs of XML documents for equivalence; for this purpose, the Canonical XML transformation removes non-meaningful differences between the documents. 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: In converting an arbitrary XML document to Canonical XML, attributes are encoded in
153-481: Is different from Wikidata Canon (basic principle) This principle of grouping has led to more specific uses of the word in different contexts, such as the Biblical canon (which a particular religious community regards as authoritative) and thence to literary canons (of a particular "body of literature in a particular language, or from a particular culture, period, genre").

238-452: The same canonical form, then the two documents are logically equivalent within the given application context (except for limitations regarding a few unusual cases). However, in a special context users might care about special semantics beyond the generic logical equivalence with which Canonical XML is associated. For example, a steganography system could conceal information in an XML document by varying whitespace, attribute quoting and order,

Such contexts are beyond the scope of Canonical XML. This markup language article
