Answer 1

As long as your template match refers to wildcards like *:

<xsl:template match="*[*]">

you do not have to worry about namespaces. However, if you match specific elements from your input XML like here:

<xsl:template match="@*|elements/*">

you have to adhere to the default namespace specified. The following line defines a default namespace:

<plans xmlns="http://test.org/schema/product/v1">

which is passed on to all child elements as well. In other words, the element element has a namespace, too. As far as the XSLT processor is concerned, v1:element and element are entirely different elements.

By the way,

• you do not need to select all attributes (@*) because they are not matched anyway.
• in your context (template match for children of elements elements) an expression like elements/child::*" selects all children of the children of a child of an elements element that are called "elements". Which is confusing and not what you want, I think.
• as can be seen from the second remark, please avoid giving elements names like "elements" and "element" whenever possible

Stylesheet

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:v1="http://test.org/schema/product/v1"
   exclude-result-prefixes="v1">

    <xsl:output omit-xml-declaration="yes" indent="yes" method="xml" />
    <xsl:strip-space elements="*" />

    <xsl:template match="*[*]">
        <xsl:copy>
            <xsl:apply-templates select="*[*]" />
        </xsl:copy>
    </xsl:template>

    <xsl:template match="v1:element[*]">
        <xsl:copy>
           <xsl:apply-templates select="*"/>
           <xsl:element name="reference" namespace="http://test.org/schema/product/v1"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="text()"/>
</xsl:stylesheet>

Output

<plans xmlns="http://test.org/schema/product/v1">
