Hi Manfred Staudinger; You can add additional constraints to your instance data by using the constraint[1] attribute on a bind (an invalid instance can't be submitted, so this also solves your store problem). In your example: <xf:bind nodeset="im:objektkategorie/im:vermarktungsart/@MIETE_PACHT" type="xs:boolean" constraint="boolean-from-string(.) or boolean-from-string(../@KAUF)" /> Makes the miete_pacht attribute valid if either miete_pacht or kauf is true. To show a warning you can use the alert element on the input that binds to miete_pacht attribute. In your example: <xf:input ref="im:objektkategorie/im:vermarktungsart/@KAUF"> <xf:label>Verkauf: </xf:label> <xf:alert>Either verkauf or Vermietung should be checked</xf:alert> </xf:input> Regards, Nick Van den Bleeken R&D Manager Phone: +32 3 821 01 70 Office Fax: +32 3 821 01 71 Nick_Van_den_Bleeken@inventivegroup.com http://www.inventivegroup.com 1: http://www.w3.org/MarkUp/Forms/specs/XForms1.1/index-diff.html#model-prop-constraint > -----Original Message----- > From: www-forms-request@w3.org [mailto:www-forms-request@w3.org] On > Behalf Of Manfred Staudinger > Sent: zondag 21 juni 2009 22:10 > To: www-forms@w3.org > Subject: How to ensure that at least one of 2 attributes is set to true > > Hi List, > > I'm new to XForms, read a lot but still missing something: I did not > find a solution (other than post-processing with xslt).
