Peter told you to just define the path. The definition of this path then has
to be made in a separate TypoScript template:

Only this will stay in your TV structure:

<eType_EXTRA type="array">
    <objPath>lib.btm_elm_1</objPath>
</eType_EXTRA>

And this should be the "external" TypoScript defined in the SETUP part of a
TypoScript template:

lib.btm_elm_1 = COA
lib.btm_elm_1 {
    10 = RECORDS
    10 {
        source.current = 1
        tables = tt_content
        stdWrap {
            ifEmpty.cObject < lib.element1
        }
    }
    stdWrap {
        required = 1
        wrap = <!--TYPO3SEARCH_begin--> | <!--TYPO3SEARCH_end-->
    }
}

"current = 1" will fill in the CSV list of content element IDs if any.
This will switch "stdWrap.ifEmpty" to true if there aren't any values in the
list.
Then lib.element1 will be used instead.
Both will be wrapped wit the comment for TYPO3SEARCH.
This will be stripped if there is no content at all.

@Tapio: As long as you stay on the same page with your checks, most of the
TypoScript stuff will be working as expected even with TV, since "current"
contains the necessary information.
