Re: What to do about newlines in attribute values?

I've just realised that our problem isn't just newlines in attribute
values, it is also tabs in attribute values, since XML attribute value
normalization replaces not just newlines but also tabs by spaces. So our
options are

(a) allow tabs and newlines but normalize to spaces (as in XML)
(b) disallow literal tabs and newlines
(c) allow tabs and newlines and leave them as is in the data model
