/** Interface to bind an UNO package.
    
    @since OOo 2.0
*/
interface XPackageRegistry
{
    /** binds a package URL to a <type>XPackage</type> handle.
        The returned UNO package handle ought to late-initialize itself,
        thus the process of binding must not be an expensive operation, because
        it is not abortable.

        Calling the function several time with the same parameters must result
        in returning the same object.

        The file or folder at the location where url points to may not exist or
        it was replaced. This can happen, for example, when a bundled extension
        was removed by the setup and a user later starts OOo. Then the user data
        may still contain all registration data of that extension, but the
        actual extension files do not exist anymore. The registration data must
        then be cleaned of all the remains of that extension. To to that one
        creates an <type>XPackage</type> object on behalf of that extension and
        calls <member>XPackage::revokePakage</member>. The parameter
        <code>removed</code> indicates this case. The returned object may not
        rely on the file or folder to which refers <code>url</url>. Instead it
        must use previously saved data to successfully carry out the revocation
        of this object (<member>XPackage::revokePackage</member>).

        The implementation must ensure that there is only one instance of
        <type>XPackage</type> for the same <code>url</code> at any
        time. Therefore calling <member>bindPackage</member> again with the same
        <code>url</code> but different <code>mediaType<code> (the exeption is,
        if previsously an empty string was proveded to cause the determination
        of the media type) or <code>removed</code> parameters will cause an
        exception. An <type
        scope="com::sun::star::lang">IllegalArgumentException</type> will be
        thrown in case of a different <code>mediaType</code> parameter and a
        <type>InvalidRemovedParameterException</type> is thrown if the
        <code>removed</code> parameter is different.

        The <code>identifier</code> parameter must be provided when
        <code>removed</code> = true. If not, then an <type
        scope="com::sun::star::lang">IllegalArgumentException</type> will be
        thrown.
