Add Content Block Tax Rate content type

[Harriethw]

The Content Modelling Team are working on a spike to add the ability to publishing reusable pieces of content (“Content Blocks”) via Whitehall. This adds a simple initial schema to help us work with a type of tax rate.

Added to Whitehall here: alphagov/whitehall#9278

Some things I found out:

• I wanted to make the rate field an integer and a percentage - so max 100 value. However, our current form submites everything as strings, e.g. 100 becomes "100" so we would need to do more work to make this possible.
• I was also not able to give fields a min/max length because the tests generated didn't seem to take notice of these paramteres and were generating data above the min length - would need to look into this.

This is an interesting one, because I think we're mixing up metadata and actual data here. To me, the band and the income would be metadata here, as they wouldn't actually be returned to the user. My mental model was more like we'd have two content types, tax_income and tax_rate, with individual body fields.

To use the example of a table of tax rates, I'd expect it to be used like this:

Band	Taxable income	Tax rate
Personal Allowance	{{embed:tax_income:personal-allowance}}	{{embed:tax_rate:personal-allowance}}
Basic rate	{{embed:tax_income:basic-rate}}	{{embed:tax_rate:basic-rate}}
Higher rate	{{embed:tax_income:higher-rate}}	{{embed:tax_rate:higher-rate}}
Additional rate	{{embed:tax_income:additional-rate}}	{{embed:tax_rate:additional-rate}}

That said (and this is a thing that's just occurred to me), if we went with this approach we could potentially have a more three-dimensional view and do something like this:

Band	Taxable income	Tax rate
Personal Allowance	{{embed:tax_rate:personal-allowance:income}}	{{embed:tax_rate:personal-allowance:rate}}
Basic rate	{{embed:tax_rate:basic-rate:income}}	{{{embed:tax_rate:basic-rate:rate}}
Higher rate	{{embed:tax_rate:higher-rate:income}}	{{embed:tax_rate:higher-rate:rate}}
Additional rate	{{embed:tax_rate:additional-rate:income}}	{{embed:tax_rate:additional-rate:rate}}

Which could be quite cool. I think we'd need to run this via Rik first, as well as think how this would work within the rest of the user journey. Potentially super powerful though, and would also scale to things like contacts etc too

hmm, I just thought that that entire row on this page for example could be a bit of re-usable content in other Editions https://www.gov.uk/income-tax-rates

Is there another block type that's less controversial we could use that would give us a schema with multiple fields? I think it would be really useful to have a 'straw man' to help us see how the different types work.

How about telephone number?
