rid and id

["Yves Savourel" <ysavourel@translate.com>]

Here is the wording proposed:

Before:

"These paired elements are matched by setting their rid attributes to the
same value. For example: <bpt id='2' rid='1'>xx</bpt> ... <ept id='3'
rid='1'>xx</ept> and <bx id='4' rid='2'/> ... <ex id='5' rid='2'/>."

Now:

"These paired elements are matched by setting their rid attributes to the
same value. For example: <bpt id='2' rid='1'>xx</bpt> ... <ept id='3'
rid='1'>xx</ept> and <bx id='4' rid='2'/> ... <ex id='5' rid='2'/>. If the
rid attribute is not present (in a 1.0 document for example), the attribute
id is used to match both tags. For example: <bpt id='5'>xx</bpt> ... <ept
id='5'>xx</ept>."
