XHTML size control

```
I take FlightCrew veredict on my files as if it were the Bible, but recently I
found several books that were not able to be opened on a SONY PRS-650.
They were revised with SIGIL and validated with FLightcrew as I state it should
be done in my famous (or infamous) "BBPP LARdT v1.16" (LARdT's Good practices
for getting a decent ePUB").

The issue was the size of some xhtml files (465Kb greater than SONY's limit
size of 300Kb). I know that ePUB standard has also a size limit but I can't
remember the figure in this very momemt.

Do you think you can include (at least as warning) a size limit check in
Flightcrew? I hope I'm not asking for a "rococó style bidet" feature. :-)
