| The zone filter recognizes most standard tags through HTML 3.0. It automatically extracts the following tags as zones and ignores other tags. |
| Tag | Description |
|---|---|
| <a> | anchor |
| <abbrev> | abbreviation |
| <acronym> | acronyms |
| <address> | address |
| <au> | author name |
| <banner> | banner |
| <base>f | used to resolve relative addressing |
| <blockquote> | block quote |
| <body> | body |
| <cite> | citation |
| <code> | code sample |
| <dfn> | definition |
| <fn> | footnote |
| <form> | form |
| <h1> | heading level 1 |
| <h2> | heading level 2 |
| <h3> | heading level 3 |
| <h4> | heading level 4 |
| <h5> | heading level 5 |
| <h6> | heading level 6 |
| <head> | header block |
| <html> | html zone |
| <lang> | alternate language |
| <link> | provides information relating current document to other documents |
| <note> | separated notational text |
| <person> | person element |
| <q> | quotation |
| <samp> | sample |
| <textarea> | text area of a form |
| <title> | title of page (extracted as both a field and a zone) |
| SGML documents rely on a Document Type Definition (DTD) to define their tags. Unlike HTML, different groups of SGML documents use different DTDs. In order for you to search zones in SGML documents, the administrator must have built the collection to extract zone information from the DTD. |
