I'm curious... why do you think a "dot" is acceptable? I presume that you're referring to the standard "period" or "fullstop" that occurs at 0x002E (as opposed to a similar looking character in another codepage).
Varnames look like: ( PN_CHARS_U<http://www.w3.org/TR/2011/WD-sparql11-query-20110512/#rPN_CHARS_U> | [0-9] ) ( PN_CHARS_U<http://www.w3.org/TR/2011/WD-sparql11-query-20110512/#rPN_CHARS_U> | [0-9] | #x00B7 | [#x0300-#x036F] | [#x203F-#x2040] )* #x002E is not in any of the hex ranges shown, so looking at PN_CHARS_U we see: PN_CHARS_BASE<http://www.w3.org/TR/2011/WD-sparql11-query-20110512/#rPN_CHARS_BASE> | '_' OK, it's not an underscore, so look in PN_CHARS_BASE: [A-Z] | [a-z] | [#x00C0-#x00D6] | [#x00D8-#x00F6] | [#x00F8-#x02FF] | [#x0370-#x037D] | [#x037F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] It's not a letter, and the lowest of the characters after the letter classes start at #x00C0, which is much higher than #002E. So the parser appears to be doing the right thing here.
