We have been getting XWand incidents relate to 6.5.35
"If element “UTR” in a standard namespace is declared in the DTS of an instance,
then the value of each ‘unitRef’ attribute on each fact of a type in that registry must
refer to a unit declaration consistent with the data type of that fact, where
consistency is defined by that registry."
Usually trigger when instance file contains unit type that doesn't match with data type.
For instance, assigned custom unit type "abc:area" for AreaItemType which it will generate warning after EDGAR validation.
Solution:
Create new prefix "utr" with namespace URI "http://www.xbrl.org/2009/utr"
Add new units for Area Item Type, id = "sqft", numerator = "utr:sqft"
Add new units for Volume Item Type, id="ft3", numerator = "utr:ft3"
Reference table for UTR schema, you can look up from the following link:
