XSLT 1.0: element template only allowed as child of stylesheet

Question

I am attempting to compile an XSLT 1.0 stylesheets and am getting this error:

#<RuntimeError: compilation error: element template
element template only allowed as child of stylesheet

The error seems like an obvious fix, but there's no indication in my stylesheet markup that any template element's are using are not a child of stylesheet . Below is my entire template:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="utf-8" omit-xml-declaration="yes" />

  <xsl:template match="/message">
  {
    "heading": "<xsl:apply-templates select="normalize-space(heading/text())"/>",
    "note_id": <xsl:apply-templates select="number(NoteID)"/>,
    "player_id": <xsl:apply-templates select="number(PlayerID)"/>,
    "team_id": <xsl:apply-templates select="number(TeamID)"/>,
    "first_name": "<xsl:apply-templates select="normalize-space(Firstname/text())"/>",
    "last_name": "<xsl:apply-templates select="normalize-space(Lastname/text())"/>",
    "position": "<xsl:apply-templates select="normalize-space(Position/text())"/>",
    "hot_cold": "<xsl:apply-templates select="normalize-space(HotCold/text())"/>",
    "status": "<xsl:apply-templates select="normalize-space(Status/text())"/>",
    "description": "<xsl:apply-templates select="Description/*"/>",
    "insight": "<xsl:apply-templates select="Insight/*"/>",
    "timestamp": "<xsl:apply-templates select="time_stamp/*">"
  }

  </xsl:template>

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

  <xsl:template match="text()">
  <xsl:variable name="escaped-text">
      <xsl:call-template name="replace-string">
          <xsl:with-param name="text" select="."/>
          <xsl:with-param name="replace" select="'&quot;'" />
          <xsl:with-param name="with" select="'\&quot;'"/>
      </xsl:call-template>
  </xsl:variable>
  <xsl:value-of select="normalize-space($escaped-text)"/>
  </xsl:template>

  <xsl:template name="replace-string">
      <xsl:param name="text"/>
      <xsl:param name="replace"/>
      <xsl:param name="with"/>
      <xsl:choose>
          <xsl:when test="contains($text,$replace)">
              <xsl:value-of select="substring-before($text,$replace)"/>
              <xsl:value-of select="$with"/>
              <xsl:call-template name="replace-string">
                  <xsl:with-param name="text"
                      select="substring-after($text,$replace)"/>
                  <xsl:with-param name="replace" select="$replace"/>
                  <xsl:with-param name="with" select="$with"/>
              </xsl:call-template>
          </xsl:when>
          <xsl:otherwise>
              <xsl:value-of select="$text"/>
          </xsl:otherwise>
      </xsl:choose>
  </xsl:template>

</xsl:stylesheet>

Answer 1

the apply-templates tag isn't closed properly: improper:

<xsl:apply-templates select="time_stamp/*">

proper:

<xsl:apply-templates select="time_stamp/*"/>
