You can modify the ways values of various value types (date, url, image, etc.) are rendered by adding an ex:formats attribute to any element that has ex:role. The content of an ex:formats attribute looks a bit like a list of CSS rules, e.g.,

 <div ex:formats="date { mode: medium; show: date } number { decimal-digits: 2 } item { title: expression(concat(.label, ': ', .gender)) }" ...

which looks easier to read if you spread it vertically like in CSS

 date {
   mode: medium;
   show: date
 }
 number {
   decimal-digits: 2
 }
 item {
   title: expression(concat(.label, ': ', .gender))
 }

In the example above, there are 3 rules applied to 3 value types: date, number, and item. Each rule consists of zero or more settings. A setting consists of the setting's name, a colon, and then some specifications. Settings are separated by semicolons, much like in CSS.

This now works in lens templates, but not in facets.

Reference

To specify a URL, wrap it with

 url(...)

To specify an expression, wrap it with

 expression(...)

To specify a string, wrap it with single or double quotation marks.

date

• time-zone : number in unit of hours.
• mode : short | medium | long | full; will nullify subsequent template specifications.
• template : string; will nullify subsequent mode specifications. E.g., 'dd/MM/yyyy h:mm a'

d	day of month, no zero padding
dd	day of month, padded with zero
EEE	day of week, abbreviated
EEEE	day of week, full
MM	month as number (01 - 12), padded with zero
MMM	month name, abbreviated
MMMM	month name, full
yy	year, abbreviated
yyyy	year, full
G	era ("AD" or "BC")
HH	hour of day (00 - 23), military style, padded with zero
hh	hour of AM/PM (01 - 12), padded with zero
h	hour of AM/PM (01 - 12), no padding
a	"am" or "pm"
A	"AM" or "PM"
mm	minutes in hour (00 - 59)
ss	seconds in minute (00 - 59)
S	milliseconds in second (000 - 999)

• show : date | time | date-time (default is date-time)

number

• decimal-digits : non-negative integer | -1 or default (to mean no specific limit)

text

• max-length : positive integer greater than 3 | 0 or none (to mean no specific limit)

image

• tooltip : expression evaluated against current item | string
• max-width : positive integer | -1 or 0 (to mean no specific limit) not yet implemented
• max-height : positive integer | -1 or 0 (to mean no specific limit) not yet implemented

url

• target : string | none
• external-icon : url | none not yet implemented

item

• title : expression | default (for the default rendering using the label property)

currency

• negative-format : [ red | parentheses | signed | unsigned | no-parentheses | black ]+
• symbol : string | default (for the locale's default symbol) | none (for no symbol)
• symbol-placement : first | last | after-sign
• decimal-digits : non-negative integer | -1 or default (to mean no specific limit)

list

• separator : string
• last-separator : string
• pair-separator : string

The defaults for these settings are dependent on the locale. For English, separator is ", ", last-separator is ", and ", and pair-separator is " and ".
