Error and debugging modes could be ste to three different values.

<em>param.key.name=value</em> where <em>key</em> is the key of a loaded
stylesheet.<br />
+ Moreover, it is possible to specify a <em>profile</em> that is searched for
+ additional global and local parameters. The parameters stored in the profile
+ have lower precedence with respect to those provided in the URL. A

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 />
