That is valid per the XML Schema definition for the 'xs:duration' type [1].

"... The number of seconds can include decimal digits to arbitrary
precision.

... Similarly, the value of the Seconds component allows an arbitrary
unsigned decimal. Following [ISO 8601]
<https://www.w3.org/TR/xmlschema-2/#ISO8601>, at least one digit must
follow the decimal point if it appears. That is, the value of the
Seconds component must conform to the pattern |[0-9]+(\.[0-9]+)?|.  ...  "

As to whether the various libraries that we use actually parse and use
that correctly, I can't confirm with certainty without going and
looking and/or testing.  But I would say that if you're doing it and
it's now throwing an error, that's a good sign.
