mdex:string properties represent character strings.
An mdex:string property represents variable-length character strings. The characters should conform to the specification for valid XML characters, as described in the W3C XML document at this URL: http://www.w3.org/TR/REC-xml/#charsets
Keep in mind that mdex:string is the default property data type. That is, if you do not explicitly specify the property type when creating a standard attribute, then mdex:string will be used as the property type of the Dgraph record for that attribute.
