In XMP, is there a frame alternative to timeValue

trying set value api, , i'd rather set frame value time value.

in alttimecode:timevalue i'd set 101 instead of 00:00:04:05 , in alttimecode:timeformat, i'd set 'frames'

 

however, manually setting these values through code doesn't work.
does premiere read in values in format?
according spec, these possible values field:

    // options going (from xmp spec pdf):

        23976timecode

        24timecode

        25timecode

        2997droptimecode (semicolon delimiter)

        2997nondroptimecode

        30timecode

        50timecode

        5994droptimecode

        5994nondroptimecode

        60timecode
but i'm hoping there's potentially field, alternative field alttimecode:timevalue , alttimecode:timeformat. otherwise, have convert them myself i'm doing, think safer use frames i've been doing already.

 

 

         <xmpdm:starttimescale>24000</xmpdm:starttimescale>

         <xmpdm:starttimesamplesize>1001</xmpdm:starttimesamplesize>

         <xmpdm:starttimecode rdf:parsetype="resource">

            <xmpdm:timevalue>00:00:00:00</xmpdm:timevalue>

            <xmpdm:timeformat>23976timecode</xmpdm:timeformat>

         </xmpdm:starttimecode>

         <xmpdm:alttimecode rdf:parsetype="resource">

            <xmpdm:timevalue>00:00:04:05</xmpdm:timevalue>

            <xmpdm:timeformat>23976timecode</xmpdm:timeformat>

         </xmpdm:alttimecode>

there no additional field. i've asked xmp team chime in.
