I've decided to make at least one more change to the Canonicalizer API. I'm going to remove the write(Nodes, String inclusiveNamespacePrefix) method. Instead, I'm going to add a setInclusiveNamespacePrefixes method. The reasons are two-fold:

1. The inclusiveNamespacePrefixes only matter when doing exclusive XML canonicalization.

2. I'm afraid that future canonicalization algorithms may add additional, per-document options, like a list of attributes to inherit, and I don't want the number of methods to grow exponentially to support them all.

One question that arises though. now that it's a separate option, should I just use addInclusiveNamespacePrefix and removeInclusiveNamespacePrefix, each of which would operate on a single prefix, rather than setting them all at once as a string?

In practice, I don't expect more than two or three inclusive prefixes per document at most; and most applications will probably reuse the same prefixes repeatedly.
