I looked through this and it does exactly what Tatu suggested, but it doesn't seem to address what I'm looking for, dynamically fetching data based on what is in the xsl stylesheet. This simply skips the generation and parsing of an XML source, instead emitting SAX elements directly, but still statically with respect to what a given stylesheet requires.
Here's a scenario, a data set consisting of enormous amounts of financial transactions, tied to personal data. For both security and size reasons, the data cannot be exposed as a data source to be manipulated by xslt transformations. But a set of aggregator functions can be used to generate statistics, for instance "get the distribution of transactions relative to income over the past 3 months". This derived data set can then be further manipulated by xslt. But there is no way to predict what derived data a given style-sheet will request, so it needs to be fetched dynamically. DOM and SAX aren't designed to do this, but the XPath API *appears* to be - I just can't for the life of me figure out how to make it work as a source.
