This is intentional to have the <meta> tag uniformily be inherited by nested tags.
To avoid having the implements tag "inherit" further down you just add an attribute inherit="false" on it - then it will not be inherited down to composite id's.

I know the default inheritance of meta sometimes causes "funny" effects - but we have made the inheritance "rule" as simple as possible (namely: "ALWAYS inherit meta, except if inherit=false") thus you get the easy feature of just saying: <meta attribute="scope-field">protected</meta> just ONCE in the hbm.xml.

But if you got more "complex" hbm.xml files then you'll have to be more explicit about it.....hope ya' understand ;)

        Key: HB-242
    Summary: <meta attribute="implements"> does not behave as expected
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
 Components: 
             toolset
   Versions:
             2.0.1

Environment: JDK1.4

Description:
If the tag <meta attribute="implements">com.hp.Printer</meta> is inserted as a child of the class tag it properly adds the implement clause to the class. But if that class also contained a <composite-id> tag which indicated a class then that class would also UNEXPECTEDLY implement the interface "com.hp.Printer".


So in the following example:

<class name="com.hp.ColorPrinter">
<meta attribute="implements">com.hp.Printer</meta> 
<composite-id
        name="propertyName"
        class="com.hp.PrinterId">

        <key-property name="propertyName" type="typename" column="column_name"/>
        <key-many-to-one name="propertyName class="ClassName" column="column_name"/>
</composite-id>

Both "ColorPrinter" and "PrinterId" end up implementing "com.hp.Printer". ColorPrinter is expected to implement the interface, but PrinterId should not implement the interface.
