Provide tagged information to your listeners, not only Dynamic PS or Text. The RDS encoders with X-Command support can send complete tagged data directly from the RCS Zetta software.
In the RCS Zetta add a new export, either serial or TCP.

<xsl:strip-space elements="*"/>
<xsl:variable name="newline">
<xsl:text> </xsl:text>
</xsl:variable>
<xsl:template match="/">
<xsl:apply-templates/>

<xsl:template match="LogEventCollection">
<xsl:for-each select="LogEvent">
<xsl:text>XCMD=<rds><item><dest>3</dest><text></xsl:text>
<xsl:choose>
<xsl:when test="@Type='SONG'">
<xsl:text><title></xsl:text>
<xsl:value-of select="Asset/@Title"/>
<xsl:text></title> - <artist></xsl:text>
<xsl:value-of select="Asset/@Artist1"/>
<xsl:text></artist></xsl:text>
