[gobo-eiffel-develop] Export status and cluster dependencies

[Colin P. A. <co...@co...>]

In order to create the XPath string value of an xs:decimal value
correctly (no exponential notation, and no NaNs or infinities), I
copied and edited the code for {MA_DECIMAL}.to_string_general into
XM_XPATH_DECIMAL_VALUE.

In order for it to compile, I had to add XM_XPATH_DECIMAL_VALUE to the
list of classes to which {MA_DECIMAL}.coefficient is exported.

I am not sure if doing this adds an unwanted cluster dependency or not
(I have a vague memory that ECMA miht have changed the rules in this
area). If it does introduce a dependency, then instead coefficient
will need exporting to ANY.

I haven't checked this code in.
