I think that we can just add the following at the end of this mapping
section:

"Values of attributes which corresponds to XML Schema decimal data type
MUST be in addition also *valid floating-point numbers* as defined in
[HTML5]."

Effectively this will prohibit using leading/trailing whitespace and
also it will prohibit using exponential notation for numbers in HTML
serialization of ITS (because this is not allowed in xsd:decimal).

If we want to allow exponential notation in HTML serialization, then I
think we should use xsd:float in XML serialization of ITS as well.

Henri, do you think this resolves your concerns?
