I was wondering if full XSLT or a subset of it is supported and how the whole thing stands against Streaming Transformations for XML. Streaming processing does only apply to a certain subset of XSLT and XPath; for example, an expression like "(//a)[count(//a) div 2]" can't be evaluated on a stream of input data without buffering the entire stream, thereby defeating the purpose. DataPower's XA35 does streamability analysis on each stylesheet, and if it finds expressions that can't be executed on a stream, it logs diagnostics to that effect and falls back to normal tree-oriented processing. This technology has no particular relation to STX. Jan
