XQuery 0.9-ml Deprecated
The XQuery 0.9-ml dialect has been deprecated and will no longer be supported in a future release. MarkLogic recommends that you port any legacy 0.9-ml XQuery code to either enhanced XQuery dialect (1.0-ml) or strict XQuery dialect (1.0). For more information, see Porting 0.9-ml XQuery Code to Enhanced 1.0-ml in the XQuery and XSLT Reference Guide.
Template Driven Extraction (TDE) functions are also affected by this deprecation. The function cts:valid-index-path may throw error messages if you do not upgrade your code to XQuery dialect 1.0-ml or 1.0.
