Contradicting sentences about `core:require` in Fragments about openui5-docs

[stopcoder]

Hi @boghyon,

with the last paragraph in Require Modules in XML View and Fragment, we want to point out that the core:require on FragmentDefinition doesn't work when the view where the fragment is used is preprocessed. The preprocess here means that either preprocessor is registered to XMLView or the preprocessors option is set when creating a XMLView instance, details can be seen here. The Fragment is not defined inline in the XMLView but in a separate location.

What you found here is another case where the core:require doesn't take any effect when writing the FragmentDefinition inline within a View definition. This isn't mentioned in the documentation and should be added there.

In both of the cases where the core:require doesn't have any effect, the FragmentDefinition node isn't included in the created XMLView instance. Therefore the core:require attribute in the FragmentDefinition isn't available for its child nodes.

I will rewrite the paragraph regarding core:require in Fragment and explicitly state that the core:require doesn't work on FragmentDefinition node when:

• The View where a fragment is used is preprocessed
• A fragment is defined inline in a View

Best regards,
Jiawei

Now I get it.

This works:

_{src: https://jsbin.com/luzekib/edit?js,output}

<core:FragmentDefinition xmlns:core="sap.ui.core"
  core:require="{
    IntegerType: 'sap/ui/model/type/Integer'
  }">
  <!-- ... -->
</core:FragmentDefinition>

Whereas..

This doesn't:

_{src: https://jsbin.com/baxetik/edit?js,output}

<mvc:View xmlns:mvc="sap.ui.core.mvc">
  <core:FragmentDefinition xmlns:core="sap.ui.core"
    core:require="{
      IntegerType: 'sap/ui/model/type/Integer'
    }">
    <!-- ... -->
  </core:FragmentDefinition>
</mvc:View>

---

TBH, the mentioned paragraph is a bit confusing since it begins saying that core:require works on the FragmentDefinition node, and the next sentences deny it right away.
