Without looking too closely, first you should always declare the type
and cardinality of the function's return value, so change:

>   <xsl:function name="f:f_UpperLowerCaseFix">

to <xsl:function name="f:f_UpperLowerCaseFix" as="xs:string">

(a single string)

>     <xsl:param name="p_String" />

...you should also declare the type and cardinality of the param but
that's likely to be a side issue here.

So, with the function's return type declared as a single string, the
processor will throw an error as soon as the second item in the
sequence is added (before it ever gets to the concat function) - with
good xsl:message output or the help of a debugger you should be able
to determine where the problem is.
