Note the following tag conventions:
Classes for tags belong to the package com.sun.web.search.taglibs.
All the pageContext attributes have the prefix com.sun.web. The attribute for search result for example, is com.sun.web.searchresults.form_id where form_id is the name of the form.
Tag libraries are referenced with the prefix s1ws. Names of tags and their attributes are in mixed case with the first letter of each internal word capitalized, for example, pageContext.
