21 <p>An entry in the catalog is interpreted as follows:<list>
|
|
|
22 <item><p>The PUBLIC keyword indicates that an entity manager should use the
|
|
|
23 associated <keyword>storage object identifier</keyword> to locate the entity
|

24 text for an entity with the specified public identifier.</p></item>

26 associated <keyword>storage object identifier</keyword> to locate the entity
|

27 text for an entity with the entity name specified by the <keyword>entity name
|
|
|
28 spec</keyword>.</p></item>
|
|
|
29 <item><p>The DOCTYPE keyword indicates that an entity manager should
|
|
|
30 use the associated <keyword>storage object identifier</keyword> to
|
|
|
31 locate the entity text (to be used as the external subset) for a
|
|
|
32 doctype declaration whose document type name is specified by the
|
|
|
33 <keyword>entity name spec</keyword>.</p></item>
|
|
|
34 <item><p>The LINKTYPE keyword indicates that an entity manager should use

35 the associated <keyword>storage object identifier</keyword> to locate the
|
|
|
36 entity text (to be used as the external subset) for a linktype declaration
|
|
|
37 whose link type name is specified by the <keyword>entity name spec</keyword>.
|

|
|
|
39 <item><p>The SGMLDECL keyword indicates that an entity manager should use
|
|
|
40 the associated <keyword>storage object identifier</keyword> to locate the
|
|

41 entity text to be used as the SGML declaration.</p></item>
|
|
|
42 <item><p>The DTDDECL keyword indicates that an entity manager should
|
|
|
43 use the associated <keyword>storage object identifier</keyword> to
|
|
|
44 locate the entity text to be used as the SGML declaration. Note that
|
|
|
45 the <keyword>public identifier </keyword> in a DTDDECL entry is meant
|
|
|
46 to match a public identifier given as part of the doctype declaration
|
|
|
47 to reference the external subset.</p></item>
|
|
|
48 <item><p>The DOCUMENT keyword indicates that an entity manager should use

49 the associated <keyword>storage object identifier</keyword> to locate the

|
50 entity in which parsing begins.</p></item>
