Control single element using two xsd

Question

Can we control the single element using two, three xsd.

<html>
  <head>
    <title> </title>
  </head>
  <body>
  </body>
</html>

I have an xsd to control the above structure.

<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="html" type="Root" />
<xs:complexType name="Root">
    <xs:sequence>
        <xs:element name="head"/>
        <xs:element name="body" type="xs:string" minOccurs="1"/>
    </xs:sequence>
</xs:complexType>

I can call this as base xsd. I am creating another two xsd to control body element attribute values and allow one project1 element in the body, and in another xsd I want to project2 new element within body using base included base.xsd. How this can be done? Is this achievable?

It's unconventional, but there's nothing stopping you from validating an XML document once with one XSD and again with a different XSD. Note that @schemaLocation and @noNamespaceSchemaLocation won't be sufficient to associate the additional XSDs to be successively applied; you'd have to make the additional associations between the XML document and the XSDs externally.

More commonly, however, a single XSD will be used for validation. That XSD might itself consist of other included or imported XSDs. (See: What's the difference between xsd:include and xsd:import?) If you're new to XSD and are looking to modularize your XSD design, I suggest you pursue this more conventional approach to organizing and composing XSDs.
