       Body:
well - then you just use the inherit="false" on every meta tag you got.

I agree that sometimes the ineritance does not make sense, but at other times it does (like scope-get, scope-field etc.)

The default of having inherit="true" was made after asking the community what they thought - should i change the default behavior of meta (breaking existing code) ? And guess what, noone answered ;)

So, i kept the default. But please, make an jira issue on the subject and then if it gets enough votes i'll consider changing the default.

        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.
