Added some info on unitPatterns in tr35-general that I hope is helpful, partly in addressing some of the issues raised in the JIRA ticket:

1. Near the beginning of section 6 Unit Patterns, added:

The elements may be used to format quantities with decimal values; in such cases the choice of plural form will depend not only on the numeric value, but also on its formatting (see Language Plural Rules). In addition to formatting units for stand-alone use, elements are increasingly being used to format units for use in running text; for such usages, the new Grammatical Features information will be very useful.

Note that for certain plural cases, the unit pattern may not provide for inclusion of a numeric value—that is, it may not include “{0}”. This is especially true for the explicit cases “0” and “1” (which may have patterns like “zero seconds”). In certain languages such as Arabic and Hebrew, this may also be true with certain units for the plural cases “zero”, “one”, or “two” (in these languages, such plural cases are only used for the corresponding exact numeric values, so there is no concern about loss of precision without the numeric value).

2. At the end of section 6.5 on Unicode Sequences:

In such sequences, decimal values are typically only used with the last element of the sequence, if at all.

Sorry, I was on my phone, and it somehow didn't record an additional comment.

Please change to:

In such as sequence, decimal fractions are typically only displayed for the last element of the sequence, if at all.

Yes, that is better, thanks, made that change too
