Many of the developed prototypes use XSL Transformations (XSLT) as their foundation. However, not all XSLT processors are created equal. Some may only support a particular version of XSLT, or may not support Schema-awareness (SA). The following table lists each product and the XSLT features required.
| Product | XSLT1 | XSLT2 | XSLT3 |
|---|---|---|---|
| CVR Prototype | x | ||
| JSON-to-XML | x | ||
| XML-to-JSON | SA | ||
| Streaming CVR | x* | ||
| Schematron Rulesets | SA |
[*] Requires a processor with the streaming feature, if streaming is desired
Efforts have been made to use new features only when necessary, to ensure compatibility with as many processors as possible.
Below is a list processors tested for use by the CDF Prototypes. There are several others available.
