Chris, I would really like to see an acknowledgement from Glenn that there are some imperfections that need addressing. I wasn't aware I had given anyone the impression of presenting a perfect submission. In fact, one of my favorite quotes is Voltaire's *le mieux est l'ennemi du bien* "the best [perfect] is the enemy of the good", which a former colleague Charlie Sandbank (now deceased) used to love to cite at least once a day in ITU committee meetings.
My coding philosophy is by and large based on a step-wise refinement process: (1) make it (some subset of possible features) work (2) make sure its correct (and regression testable) - or if following BDD, then do this first (3) make it (more) understandable/maintainable, i.e., re-factor, improve comments, documentation, etc (4) optionally, make it faster and smaller (5) optionally, add more features (6) go to (1) Right now, I've finished steps (1) and (2) to a certain degree for an initial set of features, a degree that I think is sufficient to merit moving it into trunk. I have not yet seriously addressed (3) through (6). It would seem strange to expect that all these points have been addressed at this point in the process. If this work goes into the trunk, it will provide greater exposure to help drive and prioritize the remaining steps. There are trade-offs in time and money about how to spend my effort on steps (3) to (6). I have a well defined set of issues already waiting for item (5) , so, post merge, I can spend my time on these features or work on (3) or (4), or could attempt to divide my time between them. The bottom line is that it is a process that started some time ago and will continue for an indefinite time into the future. The current request for merging is just one step in that process. I expect to be maintaining this code and feature set for the indefinite future, according to the desires of my sponsor, Basis Technologies, who has a definite interest in the production use of an internationalized FOP, as well as others who have expressed a similar interest. As a consequence, there is little chance that any other FOP dev is going to have to work on this code any time soon. Of course, if they want to do so, I would certainly welcome community contributions to additional features, testing, optimization, documentation, etc., in this area. I have no personal need to *own* this code if others wish to help, and I certainly encourage it; however, at the same time, I do have a sponsor who is willing to continue investing in improving FOP in this area, and that willingness should not be discounted.  http://skynav.trac.cvsdude.com/fop/report/1 Regarding the comments about line length, file length etc., I will note that, at least with line length, I have maintained the existing (but arbitrary) limit of 100 in existing files. In the case of new files, I have chosen to use a longer line length that works better for my development process. I use GNU EMACS on a wide-screen MacBook Pro that has an effective width of 200 columns, and which, when this limit is exceeded, wraps the line (on display only). I find that arbitrary line lengths like 100 curtail my coding style, and as I've been coding for 40+ years, it's a pretty well established style (though back in the days when I wrote Fortran IV using an IBM 026 card punch<http://en.wikipedia.org/wiki/IBM_026#IBM_024.2C_026_Card_Punches>, I had to stick with 80 columns). [If line length followed Moore's Law, we would be using lines of length 1760, starting from 1967 with 80 columns.] By the way, I would note that the FOP Coding Conventions  do not specify a maximum line length. In searching through the FOP DEV archives, I also don't see an explicit discussion about line length (though I may have missed it). What I do see is the initial introduction of the checkstyle target by Jeremias in 2002 , where it appears he basically adjusted the checkstyle rules to pass most of the extant code at that time.  http://xmlgraphics.apache.org/fop/dev/conventions.html  http://marc.info/?l=fop-dev&w=2&r=1&s=%2Bcheckstyle+%2Bline+%2Blength&q=b  http://marc.info/?l=fop-dev&m=103124169719869&w=2 My opinion about the various length limits (parameter count, method length, file length, line length) as reported by checkstyle is that these should interpreted as guidelines, and not hard rules. In the case of existing files, it makes sense to attempt to adhere to them when possible (and I have done this), while recognizing that some exceptions are inevitable. In the case of new files, I agree they are reasonable targets, but I would not readily agree to slavish adherence. Some latitude should be afforded to individual coders, particularly when they are adding a substantial amount of code in new files. Regarding identifier length, neither the FOP coding conventions  nor checkstyle indicates or checks for any kind of limitation; so I will respectfully decline to change my code based on other author's subjective notions of what is necessary or sufficient. If folks want to have a discussion about this in order to reach a consensus, then I would not object to adhering to a consensus that emerges; but IMO, there are more important things to do than hammer out such a consensus in an objectively verifiable rule. What I will agree to do is add (over a reasonable period of time) comments at the point of defining all static, instance, or local variables that adequately spell out the meaning of any 'short identifier' save for the obvious indexers, i, j, k, etc, and basic type variables (String s) and enumerators (incidentally, where would one draw the line with an objective rule?).
