The issue appears to be that "transparent" is not a recognized keyword. You can work around the issue temporarily by setting the fill to an explicitly transparent value (e.g. #00000000) or to "none".

Note that while the next release will address the issue with the "transparent" keyword, there's a separate issue impacting the original sample. Element ordering is important. Styling should be defined before anything else in the document, and reference elements must come before any element that refers to it. This issue is tracked in #115.
