* This method is an extension that implements as a Xalan extension the node-set function also

* returns a node-set consisting of a single root node as described in section 11.1 of the XSLT
* 1.0 Recommendation. If the argument is a node-set, <code>nodeset</code> returns a node-set. If
* the argument is a string, number, or boolean, then <code>nodeset</code> returns a node-set
* consisting of a single root node with a single text node child that is the result of calling
* the XPath string() function on the passed parameter. If the argument is anything else, then a
* node-set is returned consisting of a single root node with a single text node child that is the
* result of calling the java <code>toString()</code> method on the passed argument. Most of the
* actual work here is done in <code>MethodResolver</code> and <code>XRTreeFrag</code>.

/**
* Adjust column widths in an HTML table.
*
* <p>The specification of column widths in CALS (a relative width plus an optional absolute
* width) are incompatible with HTML column widths. This method adjusts CALS column width
* specifiers in an attempt to produce equivalent HTML specifiers.
*
* <p>In order for this method to work, the CALS width specifications should be placed in the
* "width" attribute of the <col>s within a <colgroup>. Then the colgroup result tree
* fragment is passed to this method.
*
* <p>This method makes use of two parameters from the XSL stylesheet that calls it: <code>
* nominal.table.width</code> and <code>table.width</code>. The value of <code>nominal.table.width
* </code> must be an absolute distance. The value of <code>table.width</code> can be either
* absolute or relative.
*
* <p>Presented with a mixture of relative and absolute lengths, the table width is used to
* calculate appropriate values. If the <code>table.width</code> is relative, the nominal width is
* used for this calculation.
*
* <p>There are three possible combinations of values:
*
* <ol>
* <li>There are no relative widths; in this case the absolute widths are used in the HTML
* table.
* <li>There are no absolute widths; in this case the relative widths are used in the HTML
* table.
* <li>There are a mixture of absolute and relative widths:
* <ol>
* <li>If the table width is absolute, all widths become absolute.
* <li>If the table width is relative, make all the widths absolute relative to the
* nominal table width then turn them all back into relative widths.
* </ol>
* </ol>
*
* @param context The stylesheet context; supplied automatically by Xalan
* @param xalanNI
* @return The result tree fragment containing the adjusted colgroup.
