XSLTMethod associates XSLT transformers with XML documents. XSLTMethod automatically transforms an XML document via XSLT, where the XML document is obtained from another Zope object (the 'source' object) via acquisition.

If it is present, caching may be done. If applicable, the XSLTMethod will use the CacheManager it finds via this method The current policy is as follows: use the first cache manager found by acquisition. Alternatively, a more complex policy could be used such as a) looking in some predefined place, where the place could be specified in some property (a la Zope3 explicit acquisition), or b) finding all cache managers in the ZODB and presenting a list for selection by the user. For right now, we don't want to over-engineer the damn thing.
