Revision 46157 of Elements

<p>
{{ XsltRef() }}
There are two types of elements discussed here: top-level elements and instructions. A top-level element must appear as the child of either <code>&lt;xsl:stylesheet&gt;</code> or <code>&lt;xsl:transform&gt;</code>. An instruction, on the other hand, is associated with a template. A stylesheet may include several templates. A third type of element, not discussed here, is the literal result element (LRE). An LRE also appears in a template. It consists of any non-instruction element that should be copied as-is to the result document, for example, an <code>&lt;hr&gt;</code> element in an HTML conversion stylesheet.
</p><p>On a related note, any attribute in an LRE and some attributes of a limited number of XSLT elements can also include what is known as an attribute value template. An attribute value template is simply a string that includes an embedded XPath expression which is used to specify the value of an attribute. At run-time the expression is evaluated and the result of the evaluation is substituted for the XPath expression. For example, assume that a variable "<tt>image-dir</tt>" is defined as follows:
</p>
<pre>&lt;xsl:variable name="image-dir"&gt;/images&lt;/xsl:variable&gt;</pre> <p>The expression to be evaluated is placed inside curly brackets:
</p>
<pre>&lt;img src="{$image-dir}/mygraphic.jpg"/&gt;</pre> <p>This would result in the following:
</p>
<pre>&lt;img src="/images/mygraphic.jpg"/&gt;</pre> <p>The element annotations that follow include a description, a syntax listing, a list of required and optional attributes, a description of type and position, its source in the W3C Recommendation and an explanation of the degree of present Gecko support.
