The pdf file that you quote says (2.3 on P9) that:

"In order to allow a richer collection of attributes at a finer granularity, dot accepts

HTML-like labels using HTML syntax. These are specified using strings that are

delimited by < . . . > rather than double-quotes."

So, I think that my files are valid.

Furthermore, if you add double-quote around HTML labels, the HTML are not recognized by graphviz tools such as fdp or neato and the files generated by these tools use the default labels and not the HTML ones.

Thanks again for your time.

This is not valid dot format. Labels must always be quoted. You need to
write:

graph G {
"1" [label="<foo<br/>bar>",shape=box];
...

Also, I'm not sure if these trailing commas are allowed or not.
Take a look at the format specification at:
