The structure supports a total tax for the line item plus a breakdown
of how that tax was calculated. In my jurisdiction there used to be
PST and GST (provincial sales tax and goods and services tax), so
there would be a total tax and a breakdown of the two
components. Now that there is only HST, there is both the total and
a one-item breakdown, just as above. The type of tax is described in
the breakdown.
Remember that in UBL the recipient must not do any calculations on
the values received: the UBL instance conveys both the components of
a total and the total itself. The recipient should find *everything*
they need in the instance without doing any arithmetic.
I hope this helps.
