+XML Files
+In this directory you will find schema and dtd files related to the GnuCash
+xml file format.
+WARNING:  Please be aware that these files are informative only.
+GnuCash doesn't use them in any way. Their only function is to document
+(parts of) the xml data format's internals.
+Probably the most complete file is gnucash.rnc. As of November 2012, this
+is a fairly complete Relax NG representation for the GnuCash xml format.
+You could use this file to validate any gnucash xml file. But note the above
+warning. If you get validation errors on a file generated by GnuCash that
+probably means the relax ng schema is out of date or for the wrong version
+and not that the gnucash file is incorrect.
+There are a couple of ways to use the Relax NG schema:
+1. convert to xml format and then use xmllint:
+trang gnucash-v2.rnc gnucash-v2.rng
+xmllint --relaxng gnucash-v2.rng --noout test.gnucash
+2. Use the file as is with jing:
+jing -c gnucash-v2.rnc test.gnucash
+echo $?   (just to check, jing is silent on success)
+Both trang and jing can be found here:
+If you have any questions with validation errors with your files, just send
+a note on the gnucash-user at gnucash.org mailing list.
+A small note from the last author (Baptiste Carvello):
+Most probably you will find some cases where the schema is too constrained, as
+I've tried to be quite strict.
