My first thoughts are that XSLT should raise an error on this, and if Saxon

If this is a bug, I think I found it accidentally :)

Though I find Saxon's implementation about this to be reasonable (may
be we need to add some explanation to the XPath 2.0 spec inline with
Saxon's implementation).

According to me, casting (promoting) a double to float is a reasonable
operation. The only problem is, that double values larger than 32 bit
(which is the size of float) cannot be represented in a float value
space, and there will be significant loss of information. Saxon
produces the value INF as a result of this cast operation.
