Hi, how can I discriminate a Bundle.entry based on the type of the resource?
<type value="profile"/>
<path value="resolve()"/>
and
<type value="profile"/>
<path value="resource.meta.profile"/>
does not work.

try the following approach, use resource for the path:

        <element id="Bundle.entry">
            <path value="Bundle.entry" />
            <slicing>
                <discriminator>
                    <type value="profile" />
                    <path value="resource" />
                </discriminator>
                <rules value="open" />
            </slicing>
        </element>
        <element id="Bundle.entry:Composition">
            <path value="Bundle.entry" />
            <sliceName value="Composition" />
            <short value="Composition" />
            <min value="1" />
            <max value="1" />
        </element>
        <element id="Bundle.entry:Composition.resource">
            <path value="Bundle.entry.resource" />
            <min value="1" />
            <type>
                <code value="Composition" />
                <profile value="http://fhir.ch/ig/ch-core/StructureDefinition/ch-core-composition" />
            </type>
        </element>
