Add to l

22、ast paragraph: There can be an active document type only if “CONCUR YES” is specified on the SGML decla- ration. The base document type can be active only if at least one other document type is active. NOTE - Parsing with t-espect to the base document type alone is accomplished by not identifying an

23、 active document type. There can be an active link type for an entity if it has at least one link process definition. The possibility of simultaneous active link types depends on the class of link type, as follows: simple More than one simple link type can be active, in addition to any implicit and

24、explicit links. implicit Only one can be active. explicit More than one can be active only if they form a chain of processes in which the source document type of the first is the base document type, the source document type of the second is the result document type of the first, etc. The last link t

25、ype in the chain can be an implicit link. A tag can be omitted only as provided in this sub-sub-clause, and only if the omission would not create an ambiguity, and if “OMITTAG YES” is specified on the SGML declaration.

NOTE - A generic identifier speofkatim is implied for an empty start-tag prior to determining whether any tags were omitted before it. NOTE - The determlnatlon that an RE is data is made during recognition of marku

31、p. Markup recognition, wllich includes recognition of omitted tags, occurs before the determination of whether an RE can be ignored according to the ahove rules. This sequence produces lntllitive results in the normal case, where data can occur anywhere in the con- tent of an element, as in: (quote

32、I #PCDATA)* In content models where the occurrence of data is restricted, however, as in (x, #PCDATA) the situations described in items a) and b) would be treated as errors during markup recognttion. The use of such con- tent models is normally Iunnecessary and therefore not normally recommended (se

33、e 112.4). NOTE .- lnterpletation of an attrihote vn/rle /Itera/ OKINS as though the attribute were character data, regardless of its actual declared value. An attribute value other than character data is tokenized by replacing a sequence of SPACE characters with a single SPACE character and ignoring

34、 leading or trailing SPACE characters. NOTE - 1.okenization is performed Wthout regard to the original literal: for example, whether CDATA or SDATA enti- ties were used is irrelevant. An attribute value specification can be an attribufe value (that is, not an attribute value literal) only if it cont

35、ains nothing but name characters and either: a) it occurs in an attribute definition list; or b) “SHORTTAG YES” is specified on the SGML declaration. In 35, change “general entity name” to: genera/ entity name 1 genera/ entity name list 2 Changes to IS0 8879-1986 IS0 8879:1986/A1:1988(E) 7.9.4 7.9.4

37、 name of a data entity or an SGML subdocument entity. Such a name must be declared as though it occurred in a general entity reference with no name group specified (see 9.4.4.1). 7.9.4.5 In item a), change “for an” to: for a genera/ entity name list, 7.9.4.5 Add new paragraph after last paragraph: I

39、.4 A reference to a non-SGML data entity, PI entity, or SGML subdocument entity, is prohibited in replaceable character data. A reference to a CDATA entity or SDATA entity is permitted. NOTE - An effect of this sub-clause is to require that an element or marked section that is declared to be replace

40、- able character data must start and end in the same entity. Add note: NOTE - A number or number token is not a quantity but a character string, like a name or name token: therefore, “01 ” and “1 “, for example, are not equivalent. In item “b” of the note, change “must (and other elements should)” t

41、o: , or of a marked SW- tion that is ignored, must (and the content of other elements and marked sections should) In item “c” of the note, replace everything up to the right parenthesis with: For other elements and rnarked sections, the start-tag and end-tag (or marked section start and marked secti

42、on end III 59 and 60, replace “document type specification” with: name group? Replace paragraph with new text: A name group can be specified only if “CONCUR YES”, “SIMPLE YES”, “IMPLICIT YES”, or “EXPLICIT YES” is specified on the SGML declaration, and the reference does not occur within a start-tag

Before an entity name can be used, it must be declared by an entity decla

45、ration in all applica- ble DTDs, except that a general entity name that is undeclared in a particular DTD is treated as though it had been declared for the default entity if that DTD has one. The applicable DTDs depend on the context in which the entity name occurs, as follows: 2 Changes to IS0 8879

Add note and new paragraph: NOTE - A named character reference can be used to enter the first character of a delimiter string or delimiter-in-
