<h1>Streaming in XSLT</h1>
<p>Many more constructs are now acceptable in streaming templates. For full details see
<a class="bodylink" href="../../sourcedocs/streaming/streaming-templates.xml">Streaming Templates</a>.</p>
<p>Explicit support for streaming is available for the functions <code>data()</code>, <code>avg()</code>, <code>count()</code>,
<code>distinct-values()</code>, <code>empty()</code>, <code>exists()</code>, <code>min()</code>, <code>max()</code>, <code>string()</code>,
<code>string-join()</code>, <code>sum()</code>; for the operators "," and the <code>(= | != | <= | < | >= | >)</code> family,
and for the instructions <code>xsl:attribute</code>, <code>xsl:apply-imports</code>, <code>xsl:apply-templates</code>,
<code>xsl:choose</code>, <code>xsl:comment</code>, <code>xsl:copy</code>, <code>xsl:copy-of</code>, <code>xsl:document</code>,
<code>xsl:element</code>, <code>xsl:for-each</code>, <code>xsl:iterate</code>, <code>xsl:result-document</code>. Implicit support
is available for all functions and operators that process singleton items, and for many functions and instructions that operate on sequences
- such as <code>subsequence()</code>
and <code>xsl:for-each-group</code> - with the caveat that their input is buffered in memory. </p>
