I have created a content type that inherits directly from the "workflow task" content type. I deployed it as a feature and activated it. Now, I want to attach it to the "Task" list in a site, but when I select "Add from existing site content types" the custom content type is not available. I even moved it to the List Content Types group since the custom group was not an option. Here is my content type:
<ContentType Name="Item Checklist _x0023_5 _x0028_Procurement_x0029_"
ID="0x01080100B013991EFD9C4686A5FF33D3B6567138"
Group="CCMS"
Hidden="FALSE"
Description="Type N/A if not applicable">
