Streaming XML (Was RE: XML Information Set Requirements, W3C Note 18-February-1999)

[Hutchison, Nigel]

How about defining a streaming or cursor DTD 

Example instance

<cursor xmlns="somecursornamespace ...>
	<rowset xmls:ns="yourrowsetnamespace" ....>
		<ns:ticker ...
		<ns:ticker..
		<ns:ticker ..
		...
		<ns:ticker ...
            </rowset>
	<continue>
		<link xml:link="simple" name="more"
href="someURItogetthenexttickers"/>
	</continue>
</cursor>
