Use the sort.xsd schema to import sorting rules and dynamic attributes.
The <sorting-rule-campaign-assignment>
element
assigns a sorting rule to a campaign. If the specified campaign-id does
not match a campaign by ID, an error message is logged and the element is
skipped. Wildcard delete isn't supported when mode=delete.
White Space Handling
Sorting rule IDs are trimmed of leading and trailing white spaces before they are stored or exported to XML. If you store sorting rule IDs with leading or trailing white spaces, you must correct this. Though export trims the IDs, if you import them again in merge mode, you get additional sorting rules with IDs both with and without leading or trailing spaces.
