Whenever using an element or an attribute in locations where certain specific sizes matter (to avoid overflows or underflows), it would be logical to check whether the data length is considered valid. The following schema could constrain a name using a minimum and a maximum length to avoid unusual scenarios\n\nBounded code example (external data; do not execute automatically):\n```xml\n<xs:element name=\"name\">\n <xs:simpleType>\n  <xs:restriction base=\"xs:string\">\n   <xs:minLength value=\"3\"/>\n   <xs:maxLength value=\"256\"/>\n  </xs:restriction>\n </xs:simpleType>\n</xs:element>\n```\n\nIn cases where the possible values are restricted to a certain specific length (let's say 8), this value can be specified as follows to be valid\n\nBounded code example (external data; do not execute automatically):\n```xml\n<xs:element name=\"name\">\n <xs:simpleType>\n  <xs:restriction base=\"xs:string\">\n   <xs:length value=\"8\"/>\n  </xs:restriction>\n </xs:simpleType>\n</xs:element>\n```\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
