The phrase "a token expression of" is correct and usable in written English.
It can be used to indicate a symbolic or minimal gesture of something, often in the context of showing support or acknowledgment.
Example: "The donation was a token expression of their commitment to the cause."
Alternatives: "a symbolic gesture of" or "a minimal indication of".
Semantic theories normally describe general semantic rules governing expression types, whereas epistemic 2D semantics is based on a single individual's current understanding of a token expression.
It is likely that this year's International Migrants' Day will elicit token expressions of concern before we return to business as usual: keeping migrants out, blaming those in our countries already for some of our social or economic problems - while at the same time readily exploiting them as cheap labour.
The Soviet government, in an effort to shore up popular support for the war, also allowed for token expressions of nationalism with the re-publication of Armenian novels, the production of films such as David Bek (1944), and the easing of restrictions placed against the Church.
The concise spatial pattern of genes extracted from ISH images by SPEX can also be used as a token of gene expression and applied to infer a gene regulation network, as with microarray data.
What's distinctive of a contextualist approach is (i) that a token of the target expression must be located within the world considered as actual, and (ii) that the expression is assigned an extension on the basis of how it's used in that world.
Unlike the contextualist approach, therefore, the epistemic assignment principle does not explicitly require that a scenario contain a token of the relevant expression type in order to assign an extension relative to that scenario.
On this approach, a 1-intension will be undefined for possible worlds that do not contain a token of the target expression: no extension can be assigned for such worlds, not even an empty extension.
Participants were given a small bag of peanuts as a token of appreciation for their cooperation.
So how, on Davidson's view, do we get from a particular token to a unique type, i.e., from a token to an expression?
However, two cakes of soap were provided as a token of appreciation for participation.
