Create Library of multiple XSD - xsd

Question

I have a potential of having quite a lot of small XSD's containing individual types of a big project. (Components)
I also have a biggish number of XSD's requiring a large number of these individual XSD's. (Screens)
I know I could import each one of the "Components" into each "Screen" XSD. But its a lot of work to do on each one.
What I was hoping I could do is import each one of these "Components" into a single XSD (ComponentLibrary) and then just import this one "ComponentLibrary" into each "Screen" XSD.
I wrote the code that I thought may have been what was needed but it doesn't seem to want to work. I get errors that it is undeclared.
TF.xsd:
<xs:schema targetNamespace="http://namespace.com/TF"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:complexType name="TFType">
<xs:attribute name="size" type="xs:decimal" />
<xs:attribute name="colour" type="xs:decimal" />
</xs:complexType>
</xs:schema>
ComponentsLibrary.xsd:
<xs:schema targetNamespace="http://namespace.com/ComponentsLibrary"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tf="http://namespace.com/TF"
elementFormDefault="qualified">
<xs:import schemaLocation="TF.xsd" namespace="http://namespace.com/TF"/>
<xs:element name="TF" type="tf:TFType" />
</xs:schema>
Screen1.xsd:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cl="http://namespace.com/ComponentsLibrary"
elementFormDefault="qualified">
<xs:import schemaLocation="ComponentsLibrary.xsd" namespace="http://namespace.com/ComponentsLibrary" />
<xs:element name="tfTitle" type="cl:TF" />
</xs:schema>
Error I get
Screen1.xsd (8:3) Error Type 'http://namespace.com/Components:TF' is not declared.

Your components library schema declares an element TF, not a type TF, hence the error in the Screen1.xsd.
If you really want to make the TF type available in ComponentLibrary then you could use a chameleon schema approach.
TF.xsd should have no namespace
ComponentLibrary should then include (not import) TF.xsd
All types in TF.xsd are now available under the ComponentLibrary namespace
