The user agent is responsible for supplying user or context specific information. The list of user agent values can be found on the User Agent page.

• logging level
• logging messages of various levels
• error handling
• Logging setup (LogKit, Log4J, JDK14Logging)

• sax handler

• base directory
• uri resolvers
• which implementation of a particular
• LayoutManager to use

• embedding fonts
• compression in pdf
• image embedding

for the PS renderer (eventually):

• PostScript Level
• PPD to use
• binary/ascii switch

Output from FOP: - Generation statistics: Number of pages total, Number of pages of each page-sequence, page-master used for each page (could be used to control the paper bin to get paper from, important for me in conjunction with PS Renderer).

The Driver handles the XML input. The user agent information is through the FOUserAgent. We could handle logging through the user agent. Options could also be handled through the user agent, using mime type selection for renderer options.

render to more than one renderer at once (maybe not from the command line). For example you could generate a PDF for the archive and the PS for the printer in one run. It would probably be faster than converting the PDF to PostScript afterwards.

Several code pieces for resolving URLs and/or file locations are scattered all over FOP and Batik. These should be replaced with an URIResolver invocation to unify behaviour and remove redundancies.
