From direct email:

In section 3.2.4.1 of the following document http://www.w3.org/TR/xmlschema-2/#float it states that allowed special values for floats in xml files are "INF", "-INF" and "NaN".
Pyxb seems to convert "INF" to "inf". I have not tested the other values, but suspect similar behavior.
As this violates the xml standard I would like to ask kindly, whether you could fix this bug in pyxb. Other parsers fail on this value. (Tested on MSxml)

Also note constraints on canonical lexical representation that are probably not handled.

@pabigot fix #43: float/double non-number values incorrect.
There are three cases: PyXB accepts as INF, -INF, and NaN string values
that it shouldn't (issue #44); PyXB generates non-canonical literal
values for normal floating point (e.g. `0` instead of `0.0E0`) (issue
#45), and it generates non-canonical literal values for special values
(`inf`, `nan`).

Fix the last one, which is easy and non-intrusive.  Ignore the others
which are neither.
