Is it possible to define the Alignment of a Text/Number in XSLT ?

Not for text, but I had assumed one could for number. I've shown below a trick for doing text alignment.

But ... I think my test has revealed another facet of format-number() that is open for interpretation.

I was anticipating format-number(price,'####0.00') to always produce a string of 8 characters in length, yet both processors I have (XT and Saxon) are Java based and are using the Java library which is known to have other problems for this function.

Any alternative interpretations out there for the specification wording of: "digit specifies the character used for a digit in the format pattern; the default value is the number sign character (#)"? Would anyone else expect the "#" to produce a space if no digit is there? If that isn't the behaviour, then what is the utility of the "#"?
