There are a number of vendors that provide bar codefonts. Do a google 
search on "barcode fonts" and you'll find them. Several provide free trials.

Some barcode schemes do not use a check sum, the most common being "code 
39". For these barcodes you just set the font and use normal numbers, e.g.:

<fo:block font-family="Code39Demo">1234567</fo:block>

Code39Demo is one font I found--don't have the source to hand.

For other barcode schemes, you have to calculate the checksum or include 
it in the data, which you normally wouldn't do. You can do this 
calculation in XSLT but it's non-trivial (easier with exslt functions or 
you could write an extension function).

RenderX has a sample of using XSLT and pure FO to generate graphical bar 
codes, but this seems like more work than just using a font. But it does 
make for a neat parlor trick.

Cheers,

Eliot
