[support] taxonomy block id

[RobiW]

Hi

Have set up site to use taxonomy_block for some menu listings. When more
than one block is added page doesn't validate as taxonomy_block creates
blocks with the same div id's for each menu block eg

Menu Block 1
taxonomy_block_1
taxonomy_block_2
taxonomy_block_3
Menu Block 2
taxonomy_block_1
taxonomy_block_2
etc

Any way to rename each separate block ref ids so page xhtml validates or
another way round it?

regards
Rob
