- <em>key</em>
- </p>
- <p>
- <b><kbd>remove?keys=[key1,key2,...]</kbd></b><br />

- apply a chain of stylesheets, specified by <em>key1, key2, ...</em>, to an
- input document, specified by <em>uri</em>.<br />
- Error and debugging modes could be ste to three different values.
- <em>ignore</em> means that LibXSLT messages are ignored; <em>comment</em>
- meanst that LibXSLT messages are embedded in the result document inside an
- XML like comment; <em>embed</em> means that LibXSLT messages are embedded
- at the beginning of the result document (as childs of the root node) in
- XML elements in the UWOBO namespace<br />
- Additional parameters can be set for each stylesheet application: global
- parameters (i.e. parameters passed to all stylesheets) are set using
- <em>param.name=value</em> syntax, per stylesheet parameters are set using
- <em>param.key.name=value</em> where <em>key</em> is the key of a loaded
- stylesheet.<br />
- Properties of the final chain output can be set too: valueless properties
- can be set using <em>prop.name</em> syntax, others can be set using
- <em>prop.name=value</em> syntax.<br />
- Current supported properties are: %s.
