Schema Validation - s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'

I have a schema and sample XML. The xml is failing schema validation with the following error message. Can any one tell me why? I have checked the sample xml and do not see any 'e="ac'.

org.xml.sax.SAXParseException; systemId: file:/src/main/resources/schemas/Types.xsd; lineNumber: 1300; columnNumber: 6; s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw 'e="ac'.
