XML limitations

are there any restrictions for XML data stored in Tamino such as document size, element depth, recursive schemata or similar? i did not find any in the documentation…
Thanks very much

There are some, of course. I am not sure whether my information is really up-to-date, but it should not be too far from the current limitations:
element tag names must not be longer than 120 characters
not more than 4000 document types per database
document size is not really limited, but we noticed that Tamino works best with documents smaller than 20 MB
There is no restriction on nesting depth or recursive schema
Hope this helps
