Hi @Salve, welcome to StackOverflow! I've fixed a few issues in your post this time, but in the future please make sure to do the following: (1) Do not use tags in question titles; (2): try to make your question title give a clear indication of your problem; (3): do not post links to content/code, just post the code directly – Dan Field

XML tags are CaSe SenSitIve. complexType != complextype. You need to fix that throughout your schema - it's expecting to find <xs:complexType> but instead finding <xs:complextype>, which is not valid.

It looks like you will have similar problems elsewhere - for example, simpleType, maxLength are other tags that have different casing than the lower case names you've used in your schema. As you fix each error, your validation software should indicate the next error.

As Dan Field indicated, you have to take care of case in complexType (as well as in all XSD element names). However, there are many more issues to address in your XSD. Here is the complete list, followed by a completely corrected XSD:

  1. xs:complextype -> xs:complexType
  2. maxoccurs -> maxOccurs
  3. minoccurs -> minOccurs
  4. xs:attribute cannot have a xs:complexType child.
  5. mininclusive -> minInclusive
  6. maxlength -> maxLength but maxLength cannot appear as facet to restriction on xs:integer; changed to maxInclusive="99".
  7. xs:string cannot appear on xs:attribute along with the specification of a local type via xs:simpleType too.
  8. xs:simpleType -> xs:simpleType
  9. xs:attribute must appear after, not before, xs:sequence.

Here are the above corrections applied to your XSD such that no further errors remain:
