| <!-- Purpose: Test combination of key() and document() reading from stylesheet. --> |
| <!-- Elaboration: "Look-up table 1.6 is worth a close look because it uses an advanced XSLT |
| technique. It builds up the lookup-table right in the stylesheet, using a distinct namespace. |
| You can see the x:ns-to-binding elements right below the key. If you are familiar with keys, |
| you are aware that they define indices that will be built on the nodes in the original source |
| document that match the pattern in the match attribute. What is not as well known is that |
| every time an additional source document is loaded with the XSLT document() function, all keys |
| are applied to it as well. The xsl:variable...uses a special form of document() call to load |
| the stylesheet itself as an additional source document. Thus the nodes in the stylesheet that |
| match the ns-to-binding are indexed. This is a very useful technique for setting up a look-up |
| table without having to hack at the source document or depend on an additional file." --> |
