Erroneous spacebands inserted by Saxon

I have a function call in which I pass the current reference number, punctuation
that may follow the reference number, and the total number of references in the journal:
<xslt:value-of
select="cjs:format_ref_enum(regex-group(1),regex-group(2),$ref_cnt)"/>
The purpose of the function is to 'pad' the reference enumerator with enspaces when
required, output the enumerator, punctuation, and Xyvision markup: <xslt:function
name="cjs:format_ref_enum"> <xslt:param
name="ref_enum"/> <xslt:param
name="ref_punc"/> <xslt:param
name="ref_ttl"/> <xslt:variable
name="xpp-tag"
select="$pml2/journal/article/section[@name='citation']"/>
<xslt:if test="$pml1/journal/article/section[(@name='citation') and
(@pad_enum='1')]"> <xslt:variable
name="ref_ttl_chars"
select="string-length(string($ref_ttl))"/>
<xslt:variable name="ref_cur_chars"
select="string-length(string($ref_enum))"/>
<xslt:value-of select="for $i in ($ref_cur_chars + 1) to $ref_ttl_chars
return ' '"/> </xslt:if>
<xslt:choose> <!-- Return Specific Article Type Markup -->
<xslt:when test="$xpp-tag ne ''"> <xslt:sequence
select="$ref_enum"/> <xslt:sequence
select="$ref_punc"/> <xslt:sequence
select="$xpp-tag"/> </xslt:when> <!--
Return Regular Article Markup --> <xslt:otherwise>
<xslt:value-of select="$ref_enum"/>
<xslt:value-of select="$ref_punc"/>
<xslt:value-of
select="$pml1/journal/article/section[@name='citation']"/>
</xslt:otherwise> </xslt:choose>
</xslt:function> When run, in my output I receive the following:
<citation citation-type="book"> 1 .
 <ix> The enumerator is prefixed with a spaceband and
followed by a spaceband and the punctuation is also followed by a spaceband. Is this a
problem with the design of the function or an issue with saxon8-1-1?

Firstly, I suggest you always declare the return type of your functions. This forces
you to make a choice: is this function returning one string, or a sequence of strings?
If you want it to return one string, you will get a type error, because it is currently
returning a sequence of strings. To fix this type error, you will have to change the
function so that it concatenates the strings, for example by using string-join(). If you
declare it to return multiple strings, then it becomes clear that the strings must be
concatenated by the caller of the function. If you call the function from within
xsl:value-of, as you have done, then you can achieve this most simply by adding the
attribute separator="". By default, if the expression in the select
attribute of xsl:value-of returns a sequence of strings, then they are output with space
separation. Michael Kay
