It's nothing to do with the presence or absence of a schema, it's all to do
with the fact that X in namespace N is completely unrelated to X in
namespace N2, or X in no namespace.
You shouldn't get yourself into this situation where the same vocabulary of
local names is used in more than one namespace. But if you do (as RSS users
do) the best way is to write your transformation on the assumption that the
names are in a namespace, and then write a preprocessing transformation
where necessary to put them in that namespace. This is essentially a variant
on the identity transform:
<xsl:template match="*[namespace-uri()='']">
<xsl:element name="{local-name()}" namespace="the.real.namespace">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>

Subject: Re: [xsl] "xmlns" problem for transform
Dear Joris:
Thank you very much! Now the problem is PARTLY solved. After
I add the
non-default namespace for my xslt filter and all needed prefix, the
filter works well with schema assigned data files. However,
it can not
transform files without schema. An opposite problem to before.
How can I do?
cheers,

As the post's subject indicates, this is a
namespace-related problem
indeed.
The schema sets the default namespace to
"http://www.ivoa.net/xml/VOTable/v1.1";, you need to define in your
xslt a namespace with this uri and a chosen prefix (I know
'xmlns="http://www.ivoa.net/xml/VOTable/v1.1";' is already
present; you
need to add another non-default namespace declaration). e.g.
'xmlns:VOT="http://www.ivoa.net/xml/VOTable/v1.1";'
Next step is to find all element names in any xpath expression or
pattern in your xslt and add the prefix.
e.g. <xsl:for-each select="//RESOURCE/TABLE/FIELD" /> becomes
<xsl:for-each select="//VOT:RESOURCE/VOT:TABLE/VOT:FIELD"/>
