I have built some solutions using the QueryProcessor for generating filesystem reports using the supplied modules for calculating file-sizes and checksums. I hava also built a number of wrappers for calling and aggregating results from web-services. All these queries are embedded and run in our normal java-processes. 

Everything has worked out really well. And BaseX gives you access to a lot of good functionality like XQuery 3.0 and a rich set of modules. But I'm a bit curious if there are any drawback or special things to think about with using Basex as a general xquery-library like you would use Saxon for example?
