Remarks

Please note that LabelExpression either returns a field name or a simple expression set for a layer. A simple expression could be a concatenation of attribute values from two fields, for example first and last name of a parcel owner. MapServer drops any advanced expression set on the layer in the source map document and returns an empty string.
