Since web pages often have ".html" in them, I think that it would be 
inconvenient not allow DOTs inside qnames.

Err - that is at least 2 chars long.

Full productions for no trailing DOTs, but allowing DOTs inside prefixed names 
below.

## SPARQL prefixed names
## (Just for reference - unchanged)
QNAME ::= NCNAME_PREFIX? ":" NCNAME


## NCCHAR1 is XML 1.1's NCNameStartChar without the "_"
## (No change)

NCHAR ::= ...

## This is XML NCCHAR without the "." and without "_"

NCCHAR      ::=    NCCHAR1 | '_' | '-' | | [0-9]
                  | #x00B7 | [#x0300-#x036F] | [#x203F-#x2040]

## No leading "_" (blank nodes)
## Could allow a triling DOT here but that would be very confusing.

NCNAME_PREFIX ::= NCCHAR1 (( NCCHAR |".")* NCCHAR )?

## No trailing DOT
NCNAME       ::= ( "_" | NCCHAR1 ) (( NCCHAR |".")* NCCHAR )?
