BTW, this is also valid:

    <tag1>foo</tag1><!--Comment--><tag2>bar</tag2>

I'm still really unfamiliar with the internals of libxml,
but perhaps this is where the whitespace test might be
handy?

valid.c (libxml2-2.2.4), around line 3460:

    switch (cont->ocur) {
        case XML_ELEMENT_CONTENT_ONCE:
            if (ret == 1) {
                /* skip ignorable elems */
                while ((*child != NULL) &&
                       (((*child)->type == XML_PI_NODE) ||
                        ((*child)->type == XML_COMMENT_NODE))) {
                    while ((*child)->next == NULL) {
                        if (((*child)->parent != NULL) &&
                            ((*child)->parent->type == XML_ENTITY_REF_NODE)) {
                            *child = (*child)->parent;
                        } else
                            break;
                    }
                    *child = (*child)->next;
                }
                return(1);
            }
            *child = cur;
            return(0);
