Malcolm,
Export/import (se_exp) preserves whitespaces. It uses boundary space
declaration (with preserve value) for that
http://www.w3.org/TR/xquery/#id-boundary-space-decls . So, if intentionally
created node with whitespaces inside you will have that node after
export/import.
I believe that se_BulkLoadFromStream is strip boundary whitespaces by
default.
BTW, you can always check how Sedna actually stores data using se_term and
declare option se:output "indent=no";
prolog declaration.

Good question: Are the documents auto flatten when loading using Sedna

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
