Error message on ESEF guidance 2.2.6

Dear SAP Expert,

I created an iXBRL package from SAP DM (stack 1902). In SAP DM validation no error message is showed. However an external validator tool signal the following error message: Guidance 2.2.6 Technical construction of a block tag: [escapedHTMLUsedInBlockTagWithSpecialCharacters] Guidance 2.2.6 Each block tag MUST use escape=true in the tag attribute if the human readable content contains a < or & character.

I checked on the ESEF reporting manual and this error message indicates that block tags must use escape parameter equal to "true" if a "<" or "&" character is in the text. Is there this parameter somewhere in SAP DM?

Thanks a lot,

Andrea
