Can't hide the title column in a custom content type

Question

I'm building a custom content type. I've set a bunch of site columns I add to the content type. The content type is used in a custom list definition within a ContentTypeRef node.

I'm also willing to remove the OOB title column, but I can't find the correct declaration.

Here is my CT definition :

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <!-- Parent ContentType: Item (0x01) -->
  <ContentType ID="0x01006ffb64509c2341d2bff13b98859f792b"
               Name="MyCT"
               Description="My content type"
               Inherits="TRUE"
               Version="0">
    <FieldRefs>
      <FieldRef ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}"
                Name="Title"
                Hidden="TRUE"
                Required="FALSE"
                Sealed="TRUE"
                DisplayName="_hidden"
                ShowInDisplayForm="FALSE"
                ShowInEditForm="FALSE"
                ShowInFileDlg="FALSE"
                ShowInListSettings="FALSE"
                ShowInNewForm="FALSE" />
      <FieldRef ID="{82ea62ec-a683-4685-827e-c9775c42bc15}"
                Name="Other field"
                Required="TRUE"/>
    </FieldRefs>
  </ContentType>
</Elements>

I've also tried by using <RemoveFieldRef/> but the Title column is still visible on newform.aspx, and mandatory.

In my custom list definition, I bound the content type using :

<ContentTypes>
  <ContentTypeRef ID="0x01006ffb64509c2341d2bff13b98859f792b">
    <Folder TargetName="MyCT" />
  </ContentTypeRef>
</ContentTypes>

I'd appreciate a bit of help.

It's always difficult to properly hide / remove the title field, anyway if it's a content type inheriting from Item (which I bet it is based on its ID inheriting from 0x01) you can safely do the following : Set inherits to FALSE, and rely on the RemoveFieldRef to remove the title field. You won't need to re-enter its definition within the Fields node. Here is a sample of a working XML schema, consuming a content type that will remove the title field and having your custom field "otherfield" added instead.

<ContentTypes>
  <ContentType ID="0x01006ffb64509c2341d2bff13b98859f792b"Name="MyCT" Description="My Content Type" Inherits="FALSE" Version="0">
    <FieldRefs>
      <RemoveFieldRef ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" Name="Title" />
      <FieldRef ID="{82ea62ec-a683-4685-827e-c9775c42bc15}"  Name="Otherfield" Required="TRUE">
      </FieldRef>
    </FieldRefs>
  </ContentType>
</ContentTypes>
<Fields>
      <Field ID="{82ea62ec-a683-4685-827e-c9775c42bc15}" Name="Otherfield" DisplayName="Other field" Description="Other Field" Type="Text" Required="TRUE">
</Fields>
