disable-output-escaping is defined to work only on text nodes, not on
attribute nodes. I would suggest using character maps instead.

<xsl:character-map name="pi-delimiters">
  <xsl:output-character character="&pi-start;" string="&lt;?"/>
  <xsl:output-character character="&pi-end;" string="?&gt;"/>
</xsl:character-map>

<xsl:output use-character-maps="pi-delimiters"/>

then

   <input value="&pi-start;=$tid&pi-end;" name="comment" type="hidden"/>

where the entity references pi-start and pi-end are any convenient Unicode
private-use characters.
