IIRC no. See below

You can do:
<xf:select ref="validchecks" appearance="full">
<xf:label>Check if field is Present & Legible</xf:label>
<xf:item>
<xf:label>Description</xf:label
<xf:value>desc</xf:value>
</xf:item>
<xf:item>
<xf:label>Name</xf:label
<xf:value>name</xf:value>
</xf:item>
...
</xf:select>

You have to use a String array for validchecks to get all checked keys.
This is also used for prepareing all checkboxes for display with values
in validchecks switched on (have a look at the hobby part in the jxform
samples).
