Layers which introduce new dynamic sequence lengths

This is a list of layers which (potentially) create new (dynamic) sequence lengths (and thus new dimension tags).

• ConvLayer
• TransposedConvLayer
• WindowLayer
• PoolLayer
• PadLayer
• PrefixInTimeLayer
• PostfixInTimeLayer
• SliceLayer
• SliceNdLayer

(Related is the list of layers with special behavior on dynamic spatial axes.)
