# field to specify mandatory

Asked by jeromev on 2019-03-21

When using a code list item with Include 'Specify' field, is it possible to set the Specify field mandatory ? If no, how to check the value in an expression ?

Dear Jerome,  
Many thanks for your suggestion.  
The Specify field should be mandatory, we will fix this issue in the next version of Collect.  
If you need to access that field, you can write an expression like this:  

    code_attribute_name/@qualifier

E.g. an attribute can be relevant when `code_attribute_name = 'other' and code_attribute_name/@qualifier = 'something'`

Many thanks,

Dear Jerome,  
We will add it soon to the documentation of Collect, together with an exhaustive list of custom Collect XPath functions (e.g. idm:blank, idm:contains, idm:distance, math:abs and so on).  
Many thanks,

Thank you, it helps me !
Where can I find documentation on keywords such as @qualifier?
