But since there usually over 10 strings that have to be
translated on a
single page, I think it's not efficient to call document('')
10 times.
False ... the processor is obliged to cache the document tree
created by the document() function.
Not quite true. The actual requirement is that when you call document('')
twice, the same node is returned each time. Caching the document tree is the
most obvious way of meeting that requirement, but one can imagine other
ways.
