MSI Transform dramatic increase in size after small change

I created a transform file for an MSI using Orca that is about 5k. I applied the transform to an MSI open in Orca in order to change an application URL, consisting of an additional 11 characters, however when I generate the new transform file the new file is over 20k. Anyone have an idea why such a dramatic increase in size for such a small change? Or how I can go about determining what additional changes are being added?
Orca is configured to open MSIs in READ ONLY mode.
Currently running on Windows 7 Professional SP1 32-bit.

Well, adding 11 bytes to the file translating to more than 15,000 bytes in the transform seems drastic to me. I'd really like to be able to determine what is different in order to be sure unexpected/undesired changes are not being made. I appreciate your input, it just illustrates the problems having to deal with 3rd-party developers.  Thanks!

Upon closer examination I have discovered that the MSI I am creating a transform for has been revised and indeed has more rows in the "property" table, which I believe accounts for the larger transform file.  Thanks!
