128.0. "Tags nested too deep - bug?" by TOPDOC::HIDER (Paul Hider) Thu Mar 19 1987 11:51

 
  The following document get a "More than 5 nested levels of tags" error.
  This extract is from a document that worked fine under BL06 and was run
  through the converter.

    Hmmmmmm.  I'll take a look.  You only nested four deep.
    It shouldn't have complained about nesting until it saw
    two more levels...
    

    It may be the converter's fault.  Could you send the bl6
    version of the file (filename.gnc_6)?
    
    I am currently fixing a problem with the converter and the
    end result looks a little like this.

    Your <reference> tag is at the fourth level of nesting.
    (It is nested in a <quote> tag which is nested in an
    <emphasis> tag, whcih is nested in a <table_row> tag.)
    
    The definition of the <reference> tag requires that more
    tags get executed, and they start executing at nesting
    level 4.  Well, it turns out that they try to go down
    two more levels and so pretty soon we run up against the
    (arbitrary) level of 5, and attempt to go to 6.
    
    I've increased the nesting depth to 10 for the FT update.
    

     I just had this happen to me, sigh. I forgot a closing paren after
     a <reference> tag within a <table_row>.  Anyway, I couldn't find
     anything in the documentation about restrictions on nesting levels.
     There's no index or table of contents entry.  Is the restriction
     documented?  If not, it should be...
