  The context node is cleared when a function is called.  Other context
component that are affected by a call to a stylesheet function are:

    - current template rule (cleared)
    - current mode (cleared)
    - current group and grouping key (cleared)
    - current captured substrings (cleared)
    - output state (set to temporary output)

  The two first are related to applying template rules from within a
funciton (apply imports, next match, or in current mode).  The third
one is related to accessing grouping info from with a function called
from within xsl:for-each-group (the current group and grouping key are
not accessible from the context).  Same thing for the captured
substrings within an xsl:analyze-string.  And the last one is important
when writing to result document for instance (I don't know the other
implications of the output state).
