[F&O] Inconsistent formatting of error conditions

The raising of errors has an inconsistent appearance across the family of 
documents. This issue is purely editorial in nature.

XQuery 1.0, in Section 2.1.1, Static Context, states:

        If analysis of an expression relies on some component of the 
static context that has
        not been assigned a value, a static error is raised.[err:XP0001]

Appendix F, Summary of Error Conditions, states:

        err:XP0001

            It is a static error if analysis of an expression relies on 
some component of the static context that has not been assigned a value.

F&O, in Section 7.5.1, fn:contains, states:

        If the specified collation is unsuitable for this function an 
error ·may· be raised
        [collation unsuitable for this function].

Section D, Error Summary (Non-Normative), states:

        err:FOCH0004, collation unsuitable for this function

Finally, Serialization, in Section 2, Serializing Arbitrary Data Models, 
states:

        It is a serialization error if the value cannot be cast to 
xs:string.


I suggest that clauses of this nature be made more consistent in their 
style. I prefer the style used by XQuery 1.0.
