28 ;; | Canonical XML
29 ;; | =============
30 ;; |
31 ;; | This document defines a subset of XML called canonical XML. The
32 ;; | intended use of canonical XML is in testing XML processors, as a
33 ;; | representation of the result of parsing an XML document.
34 ;; |
35 ;; | Every well-formed XML document has a unique structurally equivalent
36 ;; | canonical XML document. Two structurally equivalent XML documents have
37 ;; | a byte-for-byte identical canonical XML document. Canonicalizing an
38 ;; | XML document requires only information that an XML processor is
39 ;; | required to make available to an application.
40 ;; |
41 ;; | A canonical XML document conforms to the following grammar:
42 ;; |
43 ;; | CanonXML ::= Pi* element Pi*
44 ;; | element ::= Stag (Datachar | Pi | element)* Etag
45 ;; | Stag ::= '<' Name Atts '>'
46 ;; | Etag ::= '</' Name '>'
47 ;; | Pi ::= '<?' Name ' ' (((Char - S) Char*)? - (Char* '?>' Char*)) '?>'
48 ;; | Atts ::= (' ' Name '=' '"' Datachar* '"')*
49 ;; | Datachar ::= '&' | '<' | '>' | '"'
50 ;; | | '	'| ' '| ' '
51 ;; | | (Char - ('&' | '<' | '>' | '"' | #x9 | #xA | #xD))
52 ;; | Name ::= (see XML spec)
53 ;; | Char ::= (see XML spec)
54 ;; | S ::= (see XML spec)
55 ;; |
56 ;; | Attributes are in lexicographical order (in Unicode bit order).
57 ;; |
58 ;; | A canonical XML document is encoded in UTF-8.
59 ;; |
60 ;; | Ignorable white space is considered significant and is treated
61 ;; | equivalently to data.
