add support for appearance="numbers" about enketo-xslt

Sorry, of course there are those types! I was momentarily confused by number.

What's wrong with <input type="number">? I can't remember trying it, so perhaps it just doesn't work...

This appearance is to show the number keyboard on mobile devices (tested on Chrome on Android) to make it easier to enter phone numbers. I always thought this was impossible! 🎉

@MartijnR You can also use <input type="number"/> instead of type="tel". This may be more suitable:

Android 6/Chrome 59:

• tel: numeric keypad but with letters below each number (e.g. 2 ABC), and a drop-down of phone numbers; *, # and + are all available; no , or .
• number: numeric keypad without letters, and with , and . available

iOS 10

• tel: numeric keypad with letters below each number, and +, *, '#`
• number: keyboard switched to 123 layout, so numbers, punctuation and currency symbols are available

I haven't tested with older versions of Android, but support may differ.

Ah thanks. I see "-" is also available for type="number". I didn't know that.

Having the letters on the numeric keypad and the ability to use "+", "()" makes type="tel" more attractive, I think, knowing that appearance="number" is meant for phone numbers.

I was worried that this wasn't a good fit as without , and . you can't input decimals. But I didn't realise that:

appearance="number" is meant for phone numbers

That seems unfortunate, to me! Is there an appearance for actual numbers?

Is there an appearance for actual numbers?

You mean in addition to type="int" and type="decimal" (in XForm)? No there isn't. What kind of use case?
