Usage Message: SequenceHold is an attribute which specifies that Sequence objects appearing in the arguments of a
function should not automatically be flattened out. Attributes[SequenceHold] = {Protected}

Notes: The SequenceHold attribute prevents Sequence
expressions from being spliced into the enclosing expression. For example:
In[1]:= SetAttributes[f, SequenceHold]
In[2]:= f[Sequence[x, y, z]]
Out[2]= f[Sequence[x, y, z]]
