/// Memory format tag specification.
///
/// oneDNN formats describe physical data layout. The physical layout
/// is described as a sequence of the dimensions as they are laid out in the
/// memory (from the outer-most to the inner-most). Note that this order
/// doesn't affect the logical order of the dimensions that is kept in the
/// `dims` field of the dnnl_memory_desc_t structure. The logical order of the
/// dimensions is specified by the primitive that uses the tensor.
///
/// For example, CNN 5D tensor always has its logical dimensions in the order
/// `(batch, channels, depth, height, width)`, while the physical layout might be
/// `NCDHW` (corresponds to #dnnl_ncdhw format tag) or
/// `NDHWC` (corresponds to #dnnl_ndhwc format tag).
///
/// ~~~cpp
/// int batch = 2, channels = 16, depth = 13, height = 13, width = 13;
///
/// int ndims = 5; // 5D tensor
/// dnnl_dims_t dims = {batch, channels, depth, height, width};
/// dnnl_memory_desc_t data_in_ncdhw;
/// dnnl_memory_desc_create_with_tag(
///      &data_in_ncdhw, 5, dims, dnnl_f32, dnnl_ncdhw);
///
/// // note that in both cases dims passed are the same
/// dnnl_memory_desc_t data_in_ndhwc;
/// dnnl_memory_desc_create_with_tag(
///      &data_in_ndhwc, 5, dims, dnnl_f32, dnnl_ndhwc);

///
/// Memory format tags can be further divided into two categories:
///  - Domain-agnostic names, i.e. names the do not depend on the tensor usage
///    in the specific primitive. These names use letters from `a` to `l` to
///    denote logical dimension from 1 to 12, and form the order in which the
///    dimensions are laid in memory. For instance, #dnnl_ab is used to denote
///    2D tensor where the second logical dimension (aka `b`) is the innermost,
///    i.e. has stride = 1, and the first logical dimension (`a`) laid out in
///    memory with stride equal to the size of second dimension. On the other
///    hand, #dnnl_ba is just transposed version of the same tensor: the
///    first dimension (`a`) becomes the innermost one.
///  - Domain-specific names, i.e. names that make sense only in the context of
///    a certain domain, such as CNN. This names are just aliases to the
///    corresponding domain-agnostic tags and used mostly for the convenience.
///    For example, #dnnl_nc is used to denote 2D CNN activations tensor
///    memory format, where channels are the innermost dimension and batch is an
///    outermost one. Moreover, #dnnl_nc is just an alias to #dnnl_ab,
///    since for oneDNN CNN primitives the logical dimensions of
///    activations tensors come in order: batch, channels, spatial.
///    In other words, batch corresponds to the first logical dimension (`a`),
///    channels correspond to the second one (`b`).
///
/// The following domain-specific notation applies to memory format tags:
///  - @c 'n' denotes the mini-batch dimension
///  - @c 'c' denotes a channels dimension
///  - When there are multiple channel dimensions (for example, in convolution
///    weights tensor), @c 'i' and @c 'o' denote dimensions of input and output
///    channels
///  - @c 'd', @c 'h', and @c 'w' denote spatial depth, height, and width
///    respectively
///
/// Upper-case letters indicate that the data is laid out in blocks for a
/// particular dimension. In such cases, the format name contains both upper-
/// and lower-case letters for that dimension with a lower-case letter preceded
/// by the block size. For example: #dnnl_nChw8c describes a format where the
/// outermost dimension is mini-batch, followed by the channel block number,
/// followed by the spatial height and width, and finally followed by 8-element
/// channel blocks.
