So I am facing this error while I was validating XML against XSD
Error - Line 38, 44: org.xml.sax.SAXParseException; lineNumber: 38; columnNumber: 44; s4s-elt-must-match.1: The content of 'sequence' must match (annotation?, (element | group | choice | sequence | any)*). A problem was found starting at: simpleType.
Error - Line 43, 41: org.xml.sax.SAXParseException; lineNumber: 43; columnNumber: 41; s4s-elt-must-match.1: The content of 'sequence' must match (annotation?, (element | group | choice | sequence | any)*). A problem was found starting at: simpleType.
in short
S4s-elt-must-match.1: The Content Of 'sequence' Must Match (annotation?, (element | Group | Choice | Sequence | Any)*). A Problem Was Found Starting At: SimpleType.
I am attaching my xml and xsd files for reference,

I saw online at many posts where similar bug error appeared. I checked my code, I couldn't find the problem. I thought maybe it's because of xs and not xsd, but I don't think that is the bug. I think I have put simpleType and complexType the right way. Please let me know.
I fixed the XSD. You just missed to declare both elements: emailAddress and mobileNum.
Though it is failing now to validate the input XML based on the actual values.
