Description

Style guides for English generally recommend hyphenating numbers in the range 21-99, for example "twenty-two", "fifty-three". Saxon traditionally uses a space rather than a hyphen in these numbers. (This affects, for example, xsl:number and format-integer).

Both conventions are encountered in practice, especially in titles such as "Chapter Twenty Two". Even if the hyphenated style is more common, it wouldn't be a good idea for Saxon to change its output for compatibility reasons.

When we incorporated ICU for numbering, we retained the existing convention for compatibility, post-processing the ICU output to remove the hyphens.

The standards allow a language code to contain "extensions" of the form "x-variant", and I propose we use "x-hyphen" (for example "en-x-hyphen" or "en-GB-x-hyphen" to request hyphenation of numbers. This should work in both xsl:number and format-integer.

The goal of backwards compatibility turns out to be made more tricky by the fact that ordinal numbering is currently incompatible depending on whether ICU is used. With Saxon-HE, we currently get "twenty-third", with EE, we get "twenty third".

So I'll introduce "en-x-nohyphen" to force the use of space as separator, and if neither is specified, it continues to behave inconsistently.

I have committed the change on the 9.9 branch, and have updated the documentation on the trunk.
