Re: Cardinality of inputs & outputs

/ Jeni Tennison <jeni@jenitennison.com> was heard to say:

|
| An optional pre/post-processing step. If the 'preprocess' step has a
| document on it, use it to transform the source prior to the other
| processing; if not, then just use the source as-is.

How do you do that?

| Another example is
| the 'source' input on the p:xslt2 step: not all transformations
| require source documents.

I had expected the xslt2 step to require either exactly one source
document or an initial template name, or both. I would have expected a
source with no documents on it to be an error.

I'm not sure that's justified, but it's what I would have expected.
