Most of the changes take place in the metadata section of the OPF. I did have to remove the NAV ToC and I removed the XML ToC (because this is ePub and we don't need it). Also had to delete those two files. But really, it's so very simple to go from ePub 3 to ePub 2 when the changes are just to be able to say it's an ePub 3.
Also, take a look at some of the meta property tags in the original OPF, they are just duplicating what we already have for meta tags. So why do we need these extranious duplicated property tags? We don't. There is not a single meta property tag that has any actual use. Take them all out and the ePub is not going to break. In fact, it's going to make the OPF smaller and easier to read.
