xsd:sequence: A problem was found starting at: simpleType

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,

academics.xml

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.

The errors are referring to the fact that the xs:simpleType declarations for emailAddress and mobileNum ought really be element declarations. (xs:simpleType cannot appear as a child of xs:sequence, but xs:element can.) You can retain the xs:simpleType anonymously beneath named element declarations, much like the rest of your XSD already does with xs:complexType above that point.

After making those fixes to the XSD, you'll also find that your XML fails to comply with the XSD at two points: admissionYear has a stray / char, and mobileNum follows the wrong format. Note that if you wish (123) 456-7890 to be a valid mobileNum, you'll have to update the XSD also to escape ( and ) in the xs:pattern regex.

All of the above fixes have been applied to the following XML and XSD, which now validate successfully:

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.

XSD

<?xml version="1.0"?>
