[xsl] A data provider that streams XML-formatted data?

["Costello, Roger L. costello@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Folks,

I want to create a compelling demonstration of XSLT Streaming.

I want to demonstrate stream-processing of data from a streaming data provider
(the data provider produces XML-formatted data over an extended period of
time). Do you know of such a data provider? What do you recommend?
