Is there a way to create a type alias in protobuf (proto2)?
<p>Is it possible to create aliases of protobuf's scalar types?</p>

<p>For example, I'd like to use <code>Sequence</code> in lieu of <code>string</code>, even though they would be binary equivalent.</p>

<p>My immediate goal is to make documentation (generated with protoc-gen-doc) more readily understandable.</p>

<p>Ideally, this type would be represented in languages that support type checking, but that's not necessary.</p>
