<p><strong>Design Discussion for clojure.data.xml</strong></p>

<p>Problem: There have been a slow stream of ad-hoc requests for XML features in clojure, but no unifying design.</p>

<p><strong>Issues</strong></p>
<ul>
	<li>promote (part of?) clojure.contrib.lazy-xml?
	<ul>
		<li>lazy-xml/parse-seq (optionally) relies on an external jar, <a href="http://www.extreme.indiana.edu/xgws/xsoap/xpp/">http://www.extreme.indiana.edu/xgws/xsoap/xpp/</a> Presumably that option would simply be removed for a clojure.data.xml version?</li>
		<li>lazy-xml/emit was reimplemented fairly recently to rely on java.xml.transform for all escaping, indenting, and character encoding.  This tends to be more correct than hand-rolled implementations of these, but does depend on Java's pluggable implementations of these classes leading to potentially inconsistent behavior in different Java installations.</li>
	</ul>
	</li>
	<li>translation of XML into Clojure data structures.
	<ul>
		<li>clojure.xml, c.c.lazy-xml, and enlive all share same format
		<ul>
			<li>enlive actually supports a superset of clojure.xml (namely comments) but the big overgsight in the current Clojure way to represent XML is how to deal with namespaces</li>
		</ul>
		</li>
		<li>format is code friendly</li>
		<li>could have an alternate literal-friendly form</li>
	</ul>
	</li>
	<li>improve/enhance undocumented functions in clojure.xml 
	<ul>
		<li>emit XML elements
		<ul>
			<li>indentation</li>
			<li>XML escaping</li>
			<li>CDATA sections</li>
		</ul>
		</li>
	</ul>
