Warning: Type is restricted by a facet pattern that may impede a full round-tripping of instances of this type

I always get these warnings for both my xsd:dateTime validation.

xsd:dateTime

+' <xsd:element name="ProductCreationDate" minOccurs="1" maxOccurs="1">'
+' <xsd:simpleType>'
+' <xsd:restriction base="xsd:dateTime">'
+' <xsd:whiteSpace value="collapse" fixed="true"/>'
+' <xsd:pattern value="d4-dd-ddTdd:dd:dd"/>'
+' </xsd:restriction>'
+' </xsd:simpleType>'
+' </xsd:element>'


And this warning displays on the Messages pane:

Warning: Type xs-nun(/ProductCreationDate/simpleType()) is restricted by a facet pattern that may impede a full round-tripping of instances of this type

xs-nun(/ProductCreationDate/simpleType())

pattern

Anyone knows how to get rid of this warning?

The tool, which you've not specified, is telling you that it may not be capable of round-tripping through this constraint. Remove the pattern (or really the entire restriction), if you want to remove the warning, or ignore it if you don't care about round-tripping.

pattern

restriction

Note that such round-tripping concerns are not usually reported by validating parsers. Perhaps you're using a tool that does mapping to object oriented classes (e.g. JAXB or xsd.exe) where a simple validating XML parser would suffice.
